How currency conversion works
Converting between two currencies is a ratio. Each currency in the reference table is quoted against a single anchor — the US dollar — so the table records how many units of each currency one dollar buys. To convert from one currency to another, the tool divides the destination currency's per-dollar rate by the source currency's per-dollar rate, giving a direct exchange rate, then multiplies your amount by it.
Because the conversion is purely proportional, doubling the amount doubles the result, and converting A to B then B back to A returns the original figure exactly. The exchange rate shown tells you what one unit of the source currency is worth in the destination currency.
Reading the result
The headline figure is your amount restated in the destination currency at the stored rate. The exchange-rate line shows the one-to-one conversion so you can apply it to any other amount in your head.
Remember that a higher number does not mean a currency is "stronger" — it only reflects the unit sizes. Comparing the same conversion over time is what reveals whether a currency has gained or lost value.
Why your bank may quote a different number
The rates here are static reference snapshots for estimation, not live market quotes. Real transactions almost always cost more than the mid-market rate shown:
- Banks and exchange bureaus add a spread, quoting a worse rate when you buy and another when you sell.
- Cards, transfers, and ATMs often layer on a foreign-transaction or conversion fee.
- Market rates move constantly during trading hours, so a live quote can differ from any stored snapshot.
- Always check a live source and the total fees before sending or exchanging money.

converted = amount · (rate_to / rate_from), rates per 1 USD
