Calculators on our site finally support custom exchange rates.
In order to use your own exchange rates, you need to check the “Use own exchange rates” option.
Use the appeared fields to edit the default rate.
There is a conversion direction button next to each field. By default, the direction is chosen so that the value of the exchange rate is greater than 1.
Custom rates are used in calculations only when the “Use own exchange rates” option is enabled.
