ok i times my weight by 14, so 15x14 then i add on the 1lbs, so im 15 stone 4lbs,
you do this
15 x 14 + 4= the amount of pounds you are.. 214lb,
if you want to count down from lbs to see how much weight you are in stones then
214-14 then keep pressing the = button each time you do count, when you are left with a number less than 14, count how many times you pressed = and add the remaining number, so i pressed = 15 times, and the number 4 was left, so im 214 = 15 stone 4lb
hope that wasnt to confusing!
