Feet and Inches Calculator

Taking 2 ft 9 1/2 in away from 5 ft 7 in is awkward on a decimal calculator, which is what this one is for. Enter two lengths as feet plus inches and add or subtract them, or take a single length and multiply or divide it by a number. Answers come back as feet and inches rounded to the nearest sixteenth, with the total inches, decimal feet, centimetres and metres listed alongside. Inches can be typed with decimals, so 9.5 means the same as 9 1/2.
