Exchange Rate Conversion Formula
Convert amounts between currencies using exchange rates.
Essential for international trade and travel calculations.
The Formula
Amount in Target Currency = Amount in Source Currency × Exchange Rate
An exchange rate tells you how much of one currency you get for one unit of another. Rates change constantly based on supply and demand in foreign exchange markets.
Variables
| Symbol | Meaning |
|---|---|
| Source Amount | The amount you are converting from |
| Exchange Rate | Price of 1 unit of source currency in the target currency |
| Target Amount | The equivalent amount in the target currency |
Example 1
Convert $500 USD to Euros at a rate of 1 USD = 0.92 EUR
Amount = 500 × 0.92
Amount = 460 EUR
Example 2
Convert 10,000 Japanese Yen to USD at a rate of 1 USD = 150 JPY
First find the inverse rate: 1 JPY = 1/150 USD = 0.00667 USD
Amount = 10,000 × 0.00667
Amount = $66.67 USD
