Currency Calculator
Convert between major world currencies using approximate 2024 exchange rates.
| Currency | Rate (vs USD) | Converted Value |
|---|
Convert an amount between major world currencies using fixed reference exchange rates, and see it priced out against a full table of other currencies at once.
How Currency Calculator Works
Every conversion routes through the US dollar as a common base, even when neither currency you pick is USD. The tool first divides your amount by the "from" currency's rate versus the dollar to get a USD value, then multiplies that USD value by the "to" currency's rate: amount ÷ RATES[from] × RATES[to]. The displayed exchange rate is simply RATES[to] ÷ RATES[from], and the inverse rate is its reciprocal.
Because the math bridges through USD, adding a new currency only requires one rate (versus the dollar) rather than a rate for every possible pair — the same approach real-world currency data providers use internally.
The reference table below the result reuses that same USD value to instantly show your entered amount converted into every other listed currency, so you can compare several destinations side by side without re-entering the amount. Yen and won amounts are displayed with no decimal places, matching how those currencies are typically quoted, while all others show two decimal places.

Who Uses Currency Calculator and Why
- Getting a quick estimate of what an amount in one currency is worth in another before budgeting for international travel.
- Comparing the same amount priced out across several currencies at once using the reference table.
- Checking the inverse exchange rate between two currencies without doing the division yourself.
- Roughly converting a foreign price or salary figure into your home currency for comparison purposes.
Mistakes to Avoid
- Treating the displayed rate as a live, real-time market rate — the calculator uses fixed reference rates for quick estimates, not a live feed, and actual rates change by the minute.
- Using the result to actually execute a money transfer or purchase — banks and transfer services add their own spread on top of the market rate, so this tool is for planning, not transacting.
- Not realizing every conversion routes through USD internally — if you're troubleshooting an unexpected result, remember the math is amount ÷ from-currency-rate × to-currency-rate, not a direct pairwise rate.
Tips for Best Results
- Use the reference table below the main result to compare your amount across several currencies at once instead of re-entering it repeatedly.
- Remember Japanese yen and Korean won display with zero decimal places since those currencies are conventionally quoted in whole units.
Fixing Common Problems
The conversion doesn't match what my bank or a live exchange site shows. — This calculator uses fixed reference rates rather than a live market feed, and banks/transfer services also add their own spread on top of the market rate — treat this as a planning estimate, not a transaction rate.
Terms Explained
Reference rate: A fixed exchange-rate figure used for estimation, as opposed to a constantly updating live market rate.
Inverse rate: The reciprocal of a displayed exchange rate (1 divided by the rate), showing the conversion in the opposite direction.
