If you want a digital calculator with currency conversion, the key choice is whether you need a compact calculator for quick, occasional figures or a printed record you can check later. I rank the Casio MS-80B first for everyday desk use: it combines currency and tax functions with solar power and battery backup in a small footprint. The Canon P23-DHV-3 is my pick for users who need a paper trail, a larger 12-digit display, and double-check features.

These are not live exchange-rate services: both are calculators with currency conversion functions, rather than apps that fetch current market rates. The Casio favors portability and simple operation; the Canon trades compactness and outlet-free use for printed calculations. My ranking reflects how well each product fits a typical buyer looking for a practical digital currency exchange calculator, while noting when paper records or a longer display make the Canon a better match.
Key Takeaways

More Details on Our Top Picks
Casio MS-80B Desktop Calculator with Tax and Currency Functions
The Casio MS-80B is my lead pick for buyers who want currency conversion in a calculator that remains useful for everyday office or household arithmetic. Its currency and tax functions sit alongside percentage, markup, square-root, and independent memory keys, so it can cover routine calculations without taking up much desk space. At 147 × 103 × 28.8 mm and 120 g, it is far easier to move or store than the Canon printing model.
Its most meaningful advantage over the Canon P23-DHV-3 is power flexibility. The Casio uses solar power with battery backup, while Canon requires an AC adapter. That makes the MS-80B the more practical choice for a shared desk, a home workspace, or a spot where a cable would get in the way. It also avoids the Canon’s paper-roll upkeep because it does not print, though that means there is no physical calculation record to check afterward.
The tradeoff is the 8-digit display. For ordinary conversions and basic bookkeeping, it keeps the calculator straightforward; for longer figures, the Canon’s 12-digit screen provides more room. The Casio also does not list the Canon’s double-check function, item counter, clock, or calendar. I would choose it for quick, visible calculations rather than a workflow that needs printed evidence. Neither model is described as receiving live exchange-rate updates, so buyers who need current market rates should verify the rate-setting process before purchase.
Pros:- Currency exchange and tax functions support common conversion and sales calculations.
- Solar power with battery backup reduces reliance on a nearby outlet.
- Compact, lightweight body is easy to keep on a crowded desk or put away.
- Memory, markup, percentage, and square-root keys add practical everyday functions.
Cons:- The 8-digit display has less capacity than the Canon’s 12-digit LCD.
- No printer or listed double-check feature for keeping a paper calculation record.
- The supplied details do not confirm automatic updates from live exchange-rate sources.
Best for: Home and office users who want a compact calculator with currency and tax functions, simple memory tools, and solar power with battery backup.
Not ideal for: Buyers who need printed records, a 12-digit display, or a device confirmed to fetch live exchange rates.
- Brand and model:Casio MS-80B
- Display:8 digits
- Functions:Tax calculation, currency exchange, square root, percent, markup percent, independent memory
- Power:Solar with battery backup
- Dimensions:147 × 103 × 28.8 mm

Our verdict“I recommend the Casio MS-80B for buyers who value compact, outlet-flexible currency and tax calculations more than printed records or a longer display.”
Canon P23-DHV-3 Printing Calculator with Double Check, Tax Calculation, and Currency Conversion
The Canon P23-DHV-3 is the more specialized choice: it pairs currency conversion with a two-color impact printer, a 12-digit LCD, and a double-check function. That combination is useful when the number itself is not enough and you want a printed line to review, file, or compare with another calculation. Its printer runs at up to 2.3 lines per second, and the item counter, four-key memory, clock, and calendar make it better equipped for recurring office arithmetic than the simpler Casio.
Compared with the MS-80B, Canon favors traceability and display capacity over portability. A 12-digit display leaves more space for longer figures, while printed output can make it easier to catch an entry error after the fact. The Casio is lighter and can work without an AC outlet; the Canon weighs 16 ounces and relies on its AC adapter. That difference matters if you want a calculator you can move around freely or use at a desk without an available outlet.
The paper trail comes with ongoing practical costs in time and materials: the printer needs paper rolls, and the included roll will not last indefinitely. The Canon’s AC dependence also makes it less flexible than the solar-and-battery Casio. I would select it when printed records and the double-check workflow justify those compromises, not simply because it has more features. As with the Casio, the supplied specifications list currency conversion but do not confirm that the calculator retrieves live exchange rates; buyers should not mistake conversion capability for automatic rate updates.
Pros:- Two-color printed output gives users a paper record to review or retain.
- 12-digit LCD accommodates longer figures than the Casio MS-80B display.
- Double check, item counter, four-key memory, clock, and calendar support office workflows.
- Includes an AC adapter, paper roll, and user manual.
Cons:- Requires an AC outlet, unlike the Casio’s solar power with battery backup.
- Printing depends on paper rolls and adds a recurring supply task.
- Its larger, heavier design is less convenient for portable or occasional use.
Best for: Office users who regularly need printed calculation records, double-check capability, and a 12-digit display alongside currency and tax functions.
Not ideal for: Buyers seeking a small, cordless calculator, those who do not want to maintain paper rolls, or anyone requiring confirmed live-rate updates.
- Brand and model:Canon P23-DHV-3
- Display:12-digit LCD
- Printer:Two-color impact printer, up to 2.3 lines per second
- Functions:Double check, tax calculation, currency conversion, item counter, clock, calendar
- Memory:4-key
- Power:AC adapter
- Dimensions and weight:2.2 × 6.4 × 9.1 inches; 16 ounces
- Included and warranty:AC adapter, paper roll, user manual; one-year manufacturer limited warranty
Our verdict“I recommend the Canon P23-DHV-3 when printed records and a longer display matter more than a compact footprint, outlet-free operation, and paper-free use.”
How We Picked
I ranked these two products around the stated need: a digital currency exchange calculator that can support practical calculations, rather than a dedicated exchange-rate website or phone app. I focused on the presence of currency conversion, how easily a buyer can review results, power and desk requirements, and whether each model suits quick personal use or more formal office work. The product information supplied does not establish that either device connects to current exchange-rate data, so I treat both as calculator tools and do not present them as live-rate trackers.
The Casio MS-80B ranks first because its solar-and-battery power, compact 120 g body, and combination of currency and tax functions make it the more flexible everyday desk choice. Its 8-digit display is the main limit. I placed the Canon P23-DHV-3 second overall, not because it lacks useful features, but because its printer, AC requirement, and paper use suit a narrower buyer. For someone who needs printed records or the extra display capacity, that same Canon feature set can make it the better individual choice.
I weighed documented functions and tradeoffs, not claims about conversion accuracy or rate freshness that are not included in the supplied details. Both products list currency conversion and tax calculation; the Canon adds a 12-digit display, printout, item counter, clock, calendar, and double check. The Casio instead emphasizes portability, solar operation, and a simpler footprint. I use those differences to assign each calculator a distinct role and to show who should skip it.
| currency exchange rate calculator digital | Brand and model | Functions | Power |
|---|---|---|---|
| Casio MS-80B Desktop Calculato | Casio MS-80B | Tax calculation, currency exchange, square root, percent, markup percent, independent memory | Solar with battery backup |
| Canon P23-DHV-3 Printing Calcu | Canon P23-DHV-3 | Double check, tax calculation, currency conversion, item counter, clock, calendar | AC adapter |
Factors to Consider When Choosing Currency Exchange Rate Calculator Digital
I would choose between these calculators by starting with the way you expect to use currency conversion: quick desk arithmetic, or calculations that need a visible record. The feature list matters, but rate freshness and your tolerance for a cable or paper supplies matter just as much.Check What Currency Conversion Means
Both models list a currency exchange or conversion function, but the supplied specifications do not say either one connects to the internet or refreshes rates automatically. A calculator can perform a conversion using a rate entered or configured by the user without knowing the latest market rate. If you need current figures for travel, transfers, or financial decisions, confirm how the rate is entered, how many currencies can be stored, and whether the setting persists. For live-rate access, a calculator alone may not meet your needs.
Pick a Display That Fits Your Figures
The Casio’s 8-digit display keeps the unit compact and suits many everyday sums. The Canon’s 12-digit LCD gives more room for larger numbers, which can be helpful when handling detailed office calculations. A longer display does not by itself guarantee greater conversion accuracy, but it can reduce the need to split figures across multiple operations. If your calculations commonly involve larger totals, the Canon has the advantage; if they are short and routine, the Casio keeps things simpler.
Decide Whether You Need a Paper Trail
Printed output is the Canon’s defining difference. The two-color impact printer and double-check function can help users review entries and keep a tangible record. That is a specific workflow benefit, not an automatic advantage for everyone: printing requires paper rolls and adds supplies to manage. The Casio has no printer, so it is quieter in its workflow and avoids paper, but you will need another way to preserve or verify results. Choose Canon when the record is part of the job; choose Casio when a screen result is enough.
Match Power to the Place You Work
The MS-80B’s solar power with battery backup makes it the flexible pick for a desk where outlets are limited or where you want fewer cords. Canon includes an AC adapter and depends on an outlet, which is a reasonable fit for a stationary office workstation but restricts placement. Think about where the calculator will sit, whether it needs to move between rooms, and whether a cable will be a nuisance. This practical difference may matter more than an extra memory key or calendar function.
Separate Useful Extras From Must-Haves
The Casio covers common desk needs with tax, markup, percent, square-root, and independent-memory functions. Canon’s feature set is broader for office recordkeeping, adding item counting, clock and calendar, four-key memory, and double check. I would not choose a model only because its list is longer: the right extras depend on the work. If you mainly convert figures and handle routine sums, Casio’s focused feature mix is enough. If you regularly total items and retain calculations, Canon’s added tools have a clearer purpose.
Consider Size and Everyday Upkeep
The Casio measures 147 × 103 × 28.8 mm and weighs 120 g, so it is easier to tuck away or reposition. Canon is a larger desktop unit at 2.2 × 6.4 × 9.1 inches and 16 ounces. Its printer adds a further upkeep task: replacing paper rolls. For a permanent office station, that may be a fair exchange for printed records; for occasional home use or a crowded desk, the compact Casio is more convenient. Let your routine, not the raw feature count, settle the choice.
Frequently Asked Questions
Do these calculators provide live currency exchange rates?
The supplied product details do not say that either calculator connects to a live exchange-rate source. They list currency exchange or currency conversion functions, which means the calculators support conversion work, but that alone does not confirm automatic rate updates. Before relying on either model for a current transaction, check the instructions for how rates are entered, selected, and changed.
Which calculator is better for a small desk?
I would choose the Casio MS-80B for a small desk. It measures 147 × 103 × 28.8 mm and weighs 120 g, while the Canon is a larger 16-ounce printing calculator. Casio also avoids a printer and paper roll, so it takes less space and has fewer supplies to manage. The tradeoff is its smaller 8-digit display and lack of printed records.
Is the Canon worth choosing if I do not need printouts?
If you do not need printouts, the Canon’s main distinction loses much of its practical value. Its 12-digit display, double-check feature, item counter, clock, calendar, and four-key memory may still suit a stationary office workflow, but it requires an AC outlet and paper rolls for printing. For ordinary currency and tax calculations without a paper trail, I would start with the smaller, solar-and-battery Casio.
Which model is better for larger calculations?
The Canon P23-DHV-3 has the larger display, with 12 digits compared with the Casio MS-80B’s 8 digits. That gives more space for longer figures and can make larger calculations easier to read. The display difference does not establish that the Canon uses more accurate exchange rates; rate entry and freshness remain separate questions that buyers should verify.
Can I use either calculator without plugging it into a wall outlet?
The Casio MS-80B is specified as solar-powered with battery backup, so it is the clear choice if you want to avoid depending on an AC outlet. The Canon P23-DHV-3 is listed with an AC adapter and requires an outlet for its described operation. If cord-free placement matters, Casio fits better; if printing is more important, plan for a fixed powered desk with the Canon.
Conclusion
For most buyers seeking a digital currency exchange calculator for routine home or office figures, I recommend the Casio MS-80B. Its compact body, solar power with battery backup, and useful tax and memory functions make it the more flexible everyday choice. Pick the Canon P23-DHV-3 if you are an office user who needs printed calculations, double-check support, and a 12-digit display—and accepts an AC connection and paper-roll upkeep in return. If your priority is an automatically refreshed exchange rate, neither product’s supplied details confirm that capability, so verify the rate source before choosing either one.
