Currency conversion formula

Amount in new currency = Amount in original currency × Exchange rate.

Converting from another currency to pounds

Divide the amount in the foreign currency by the exchange rate.

Inverse exchange rate

The exchange rate for converting back to the original currency (e.g., if £1 = $1.20, then $1 = £1 ÷ 1.20).
