Currency conversion multiplies the amount by the quoted exchange rate, but the practical result depends on whether the rate is base-to-target or target-to-base.

Converted amount = source amount × exchange rate

How to read the result

  • A small change in rate can matter a lot on large invoices, so always confirm the quote direction before final decisions.
  • If the result seems inverted, the rate may need to be divided instead of multiplied.

Common input mistakes

  • Using a rate quoted in the opposite direction from the amount you entered.
  • Comparing manual rates and live rates without checking the same base currency.
