UK to US Weights - Stones & Pounds to Pounds

In Britain the common measurement for a persons weight is stones and pounds, whereas in America only pounds are used. Although it is fairly simple to convert between the two it is a task that our calculator will make faster.

To convert from stones and pounds to pounds you multiply the the number of stones by fourteen and add the extra pounds. To convert from pounds to stones and pounds you need to divide the number of pounds by 14 and take the whole number of this division as the number of stones and then multiply that number by 14 and take it away from your original total pounds to find the remaining pounds.

In the first case to convert 10st 6lb to pounds multiply 10 by 14 and add 6 to get 146lb

10 x 14 + 6 = 146lb

In the second case to convert 150lb to stones and pounds divide 150 by 14, which gives 10.714. Take the whole number of this i.e. 10 to give the number of stones. Then multiply 10 by 14 to give you 140 and take this away from 150 to give you 10 pounds. So 150lb is 10st 10lb

150/14 = 10.714 for 10st

150 - (10 x 14) = 10lb
