Options
- Rate direction
- Multiply when the rate states target units per source unit. Divide to reverse that same quoted rate; do not enter an already inverted rate as well.
- Reference date
- Record the date or note supplied with your rate. It labels the scenario and does not validate the rate or retrieve a current quote.
Supported inputs and limits
Manual rates only. Amount magnitude and rate are at most 1 trillion, with at most 25 digits and 12 decimal places. The rate must be positive; negative amounts are allowed. Results display 12 significant digits with half-up rounding, using scientific notation for very small or large values. Currency-specific rounding is not inferred. Labels do not validate ISO currency codes. No live prices, spreads or provider fees are fetched.
Where your input is processed
This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.
Separate conversion arithmetic from a payment quote
A provider can apply a spread, fee or currency-specific rounding. None is inferred here. Keep the entered rate and direction with the result, then compare the amount a provider actually offers before making a payment. A negative amount is allowed for an adjustment or reversing entry.
Questions about Currency Converter
Where does the exchange rate come from?
You supply it. The page does not contact a bank or rate provider.
What if my quote uses the opposite direction?
Choose the direction matching the quote. The reciprocal helps check that choice.
Does the result include transfer fees?
No. It applies the entered rate only; account for any real fees separately.
