    It's because our calculations don't allow for the 14lbs to a stone, I always work out lbs to stone to the nearest whole stone and then add the extra lbs... not sure of the science behind it but I know exactly what you mean xxx

    just had another thought.. when I work it out on a calculator it says, say 10.9.. that's 10 (point) 9 not 10 stones 9lbs... it .9 of 14..

    Maybe i am just confusing this more lmao

    Hi emmie, the weight converter is wrong, you can't work out stones and pounds this way as it gives a percentage rather than a pound reading.

    Just work it out to the closest stone.

    It is frustrating...

    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!

    I'll try to explain

    153 divide by 14 = 10.9 (the .9 is 0.9 of a stone as there are 14 lbs is a stone not 10 so its not 9 lbs but 0.9 of a stone)

    what I do is 153 divide by 14 = 10.9

    next I say 14 x 10 = 140

    then 153 - 140 = 13

    therefore 153 = 10 stone 13 lbs

    hope that explains it

    nah its cause youre young ! youre used to dealing in decimal. not imperial measurements.

    so instead of using mulitples of 10. youre using multiples of 14.

    so the .9 is a fraction or a percentage of 14 not of 10 (which is what youre used to)

    so to get a modern calculator to do it

    divide 14lbs by 10 =1.4
    each 0.1 on your calculator = 1.4lbs

    so then multiply the 0.9x 1.4 lbs
    but remeber take out the point.( because were not using decimal here)
    so its just 9x 1.4

    total is 12.6.
    round it up to 13lbs

    if its .5 or over you can round up, if its less then .5 you round down.

    your weight at 153lbs = 10stone 12 lbs 6 oz

    its old fashioned long division :)

    i have edited this a few times, to make it sound as simple as possible.

    hope this helps

    i will do another one.

    245lbs divided by 14 = 17.5
    17 stones

    5 x 1.4 =7lbs

    17.7lbs

    try it at home folks :)

    Okay - the programmers explanation.

    The reason the calculation goes wrong when you use a calculator is that the calculator works in decimal (base 10 - 10 unit make 1 whole). Stones and Pounds is not decimal, it is base 14, where 14 units make 1 whole.

    The way I work this out is (A = Weight in Pounds):

    Stones (S) = Bit Before Decimal Point of (A / 14)
    Pounds (P) = (A - (S * 14))

    Steve
