Pounds, shillings and pence calculator

Sterling calculator







Introduction

Sadly, electronic calculators arrived too late for Britain's pounds, shillings and pence system. The first calculators went on sale in late 1970. Decimalisation was already on the way in the UK, so no-one made a sterling pocket calculator.

I wanted to see what one would have looked like if the technology had been available a little sooner, or if we had kept pounds shillings and pence until 1975.

Eyup, what about halfpennies?

£3 9s 5p

-£1 17 10½p

=£1 11s 6½p

By the time we left Primary School in 1966, we were doing those sums in our heads!

Nowadays, it's 'do what the till tells you' ;)

Sorry to say that it is not working as well it did.

Love the idea. I keep getting 'Error' when I try use any of the minus/plus buttons.

Steven

Can you give an example of what you are trying to do please? The only time I got an error with the + and = keys was when I typed the £ key first. If you do 5s 8d + 7£ it works.

Steven
Hi Gordon, Try rounding up to 6s per hour. Then you can subtract 15 pence. As 60 farthings is 15d. best regards
Gordon Rennie
I want to be able to multiply my hourly rate of 5s 11d and three farthings by 60 hours per week to get my gross salary your calculator does not allow for halfpennies or farthings
