Can anyone recommend an calculator app which can handle fractions and convert them to decimal and also metric. Does not need to be a scientific calculator but if by chance it does that would be a bonus.

You just need to buy a Casio fx-85GT Plus calculator. Annoyingly for most uses, it does its work in fractions and you need to press the S~D button to convert to everyday decimals. May also apply to other Casio models.

The first serious calculator I used was an HP21 and ever since HP calculators have been my favourite though they stopped making them years ago. However there is an excellent re-creation at:

There are versions for Windows, Mac, iPhone, Android, and Linux.

I have it on all my devices.

If you have MS Excel either on your phone or PC it easily converts fractions to decimals and back.

For example, format cell A1 as a fraction and enter 15/16. Put =A1 in cell B1 and voila it gives you the decimal equivalent, 0.9375 (rounded to 4 decimals places - more if you want).

You can work the other way by formatting A2 as a fraction and entering the formula =B2. Any decimal you then enter in B2 is converted to a fraction. You can also specify how the spreadsheet will convert decimals that are not an exact equivalent to a fraction to the nearest 1/4, 1/10, 1/16, etc up to 3 digits 1/999.

While myself and the wife were out doing our normal food shop in Morrisons I wanted a small note book for the workshop to take notes or scribble information on, anyway on the shelf I found a casio fx-85gtx calculator so that has sorted that problem also in B & M I found a small white board and pens with four magnets on thought that would be useful for writing measurements on for quick ref when milling easy wiped off after each use.

So thank you all for suggestions

I have this - printed out and laminated - hanging in my workshop - meets all needs, quick and convenient. Advantage over digital conversions that you can see 'nearest' values at a glance.
