Conversion Summary

How it works

Converted Amount = Amount × Exchange Rate. We fetch real-time rates from exchangerate.host and cache them for 12 hours to balance accuracy with performance. Swap currencies to quickly invert the conversion direction.

Inputs explained

  • Amount: The quantity of currency you want to convert.
  • From Currency: The source currency you're converting from (e.g., USD, EUR, GBP).
  • To Currency: The target currency you're converting to.
  • Swap Currencies: Button to quickly reverse the from/to currencies for inverse conversion.

Example

Amount = 100, From = USD, To = EUR. If the exchange rate is 0.92, then Converted Amount = 100 × 0.92 = €92.00. The rate 1 USD = 0.92 EUR is displayed with a timestamp.

Tips & notes

  • Exchange rates fluctuate throughout the day; rates shown are delayed and cached for 12 hours.
  • Banks and money exchangers may use different rates and charge additional fees or commissions.
