Solved Examples: Pounds to Stone
Question 1: You weigh 185 lbs. What is this in stone and pounds for a UK doctor visit?
Solution:
Divide by 14: 185 ÷ 14 = 13 remainder 3
Stone = 13, Remaining lbs = 185 − (13 × 14) = 185 − 182 = 3
Answer: 185 lbs = 13 stone 3 lbs.
Question 2: A boxer needs to make the 160 lb (middleweight) limit. Express in stone.
Solution:
Divide by 14: 160 ÷ 14 = 11 remainder 6
160 − (11 × 14) = 160 − 154 = 6
Answer: 160 lbs = 11 stone 6 lbs — the middleweight limit in UK boxing terminology.
Question 3: A UK weight loss goal is to drop from 200 lbs to 170 lbs. Express both in stone.
Solution:
200 lbs: 200 ÷ 14 = 14 stone 4 lbs (200 − 196 = 4)
170 lbs: 170 ÷ 14 = 12 stone 2 lbs (170 − 168 = 2)
Loss: 14 st 4 lbs → 12 st 2 lbs = 2 stone 2 lbs (30 lbs)
Answer: The goal is to go from 14 stone 4 lbs to 12 stone 2 lbs — a loss of 2 stone 2 lbs.
