How Currency Conversion Works
The basic conversion multiplies the amount by the exchange rate. Reverse rate is 1 / rate. Percent change can be used to show movement relative to a previous rate.
Formulas
Converted Amount = Amount × Exchange Rate
Reverse Rate = 1 / Exchange Rate
Percent Change = ((Exchange Rate - Previous Rate) / Previous Rate) × 100
