To convert pesetas to GBP, you need the exchange rate between the Spanish peseta (ESP) and the British pound (GBP). First, find the current exchange rate, which can be obtained from financial news websites or currency converters. Then, divide the amount in pesetas by the exchange rate to get the equivalent amount in GBP. Keep in mind that the peseta is no longer in use, so you may need to use historical rates for conversion.
