On the 15th February 1971 the United Kingdom converted to decimal currency - The shillings and pence element of prices were converted into 'new pence'. This application allows conversion between pre-decimal pounds, shillings and pence and the current pounds and new pence.
Of course, over the years inflation has changed the purchasing power of both old and new currency. This application uses inflation data from the Office of National Statistics to calculate calculate and equivalent purchasing power - how many £sd in a given year would have had the purchasing power of £p today, and also how many £p have the purchasing power of an amount in £sd.
The application also covers inflation in prices since 1971 - it will just give a price in decimal format.
The application can also translate between £sd and £p without applying an inflation adjustment - just enter 2010 in the year box. Useful for demonstrating how the conversion worked!
