Currency conversion and exchange rates

An exchange rate expresses how much of one currency equals one unit of another. Rates move with interest rates, inflation, trade, market demand, and economic news.

This tool retrieves rates from the site API, then converts through the provider's base currency. The displayed rate is useful for estimates; banks and card networks may add spreads or fees.

Examples

const converted = amount * exchangeRate;

converted = amount / rates[from] * rates[to]

Rate	Meaning
Mid-market	Reference rate between buy and sell prices
Bank rate	Customer rate including a spread
Spot rate	Current rate for near-immediate exchange

Practical tips

Check the timestamp before using a quote. For invoices, travel budgets, or settlement, confirm the final rate and fees with your provider.
