Using the metric scale you add your height in centimetres and your weight in kilograms

To use feet and pounds, swap to the standard calculator and add you height in feet, using a decimal not ‘ or ” so 5ft 6″ would be 5.5.

Then add your weight in pounds. Remember there are 14 pounds in a stone, so if you are 12 stone 2 pounds you would add 170 to the pounds box (12*14)+2
