Convert amounts between common currencies for quick estimates.
Fill in the fields and the result will appear here automatically.
Compare a saved reference estimate between any two supported currencies. Choose both currencies, then inspect their individual source dates before using the result as a budget estimate.
How it works
Formula and logic
Each saved coefficient b is the number of currency units per 1 USD. Result = amount × target b / source b. Saved coefficients are rounded, and the result normally shows two decimals. Different currencies may have different source dates; check each separately. This is a reference estimate without a spread or fees.
Example
Teaching example using saved data: 250 GBP × 4.76285255 / 0.75615851 = 1,574.69 RON. Actual source dates: ECB 2026-10-05. With a zero amount: 0 GBP = 0 RON.
Fields and units
- Amount — in the selected source currency
- From currency — list option
- To currency — list option
How to use
- — Enter a nonnegative amount in the source currency.
- — Choose both currencies; the result uses their saved coefficients relative to USD.
- — Check the source and date for each currency and compare a provider’s quote separately.

FAQ
How is a conversion between two currencies calculated?
The calculator uses the stored reference rates to derive a cross-rate, then applies it to the amount you enter.
Where can I see the rate date and source?
The currency page displays the date and source information for the stored rates used in the estimate.
Will a bank exchange exactly this amount?
Not necessarily. A bank or exchange service can use different buy and sell rates and add fees.
