💱 Cross Exchange Rate Calculator
Work out the implied cross exchange rate between two currencies using their exchange rates against a common base currency (typically USD).
What is a cross exchange rate?
A cross exchange rate is the exchange rate between two currencies that is derived from each currency’s rate against a third, common currency (usually the US dollar), rather than being quoted directly against each other.
How the calculation works
If you know how much of Currency A one unit of the base currency buys, and how much of Currency B one unit of the base currency buys, you can find the cross rate by dividing: Currency A per Currency B = (Currency A per Base) ÷ (Currency B per Base). The reverse rate is simply its inverse.
For example, if 1 USD buys 0.92 EUR and 1 USD buys 149.5 JPY, then 1 EUR is worth about 149.5 ÷ 0.92 = 162.5 JPY.
