Metric Value

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

  • How does this currency converter work?

    It multiplies the input amount by the exchange rate you enter. The rate should represent how much 1 unit of the source currency equals in the target currency.

    No. This tool does not fetch live data. You manually enter the rate, which allows full control and works offline.

  • What does the reverse rate mean?

    The reverse rate shows how much 1 unit of the target currency equals in the source currency. It is calculated as 1 divided by the exchange rate.

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

  • Is my data stored?
