Converted amount = amount × exchange rate. Reverse rate = 1 ÷ exchange rate.
Privacy: this converter uses only the values you type. No rates or amounts are stored or transmitted.
Currency conversion is calculated using a simple multiplication formula:
Converted amount = amount × exchange rate
How to interpret results:
- Converted amount: final value in the target currency
- Exchange rate: how much 1 unit of the source currency is worth
- Reverse rate: useful for understanding the opposite conversion
This tool is especially useful when you want to apply a known or fixed exchange rate instead of relying on fluctuating live market data.
Examples
- Travel budgeting: Convert expenses using a known exchange rate.
- Business pricing: Apply a fixed internal exchange rate for billing.
- Historical comparison: Recalculate values using past exchange rates.
Example:
- 100 USD × 1350 = 135,000 KRW
- 50 EUR × 1.08 = 54 USD
FAQ

Manual rates are useful when working with fixed contracts, historical data, or custom pricing instead of live market rates.
