How it is calculated
Amount in B = amount in A × rate(A → B) rate(A → B) = rate(USD → B) ÷ rate(USD → A)Reference rates against the US dollar come from an open service (ExchangeRate-API), updated daily, and cross rates are computed for any pair.
Rates are indicative; what you get at a bank or bureau includes a spread and fees.
Worked example
If 1 euro = 10.8 Moroccan dirhams, then 500 euros = 5,400 dirhams.
