What this means
An exchange rate tells you how much one currency is worth in another. Reference rates are set from central-bank and market feeds and are widely used for fair market conversions.
How we calculate it
Formula
Amount × (base rate ÷ quote rate). Rates come from the open.er-api reference feed.Worked example
Convert $100 to euros.
- 1Pick USD as the source currency.
- 2Pick EUR as the target.
- 3Enter 100 and read the result.
Important assumptions
- Rates are reference rates refreshed regularly, not live market ticks or your bank's buy/sell spread.
Frequently asked questions
Where do the rates come from?
From the open.er-api reference feed, which aggregates European Central Bank and other market sources for 160+ currencies.
Are these the same rates banks give?
Banks add a spread, so your final rate will differ slightly. These are fair mid-market reference rates.
