Divide pounds by 14 to get stone. 160 lb is 11.43 stone, which British readers would write as 11 st 6 lb. The table gives each weight both ways, because UK scales and forms use the stone-and-pounds format rather than decimals.

From pounds to 'stone and pounds'
For the British format, divide by 14 and keep the whole number as the stone. Multiply what's left by 14 to get the leftover pounds. For 185 lb: 185 ÷ 14 = 13.21, so 13 stone; 13 × 14 = 182, which leaves 3 lb. The answer is 13 st 3 lb. The remainder is always between 0 and 13.9 pounds.
Don't read the decimal as pounds. 13.21 st is not 13 st 21 lb (that would be over 14 st), and it isn't 13 st 2 lb either. The decimal 0.21 is a fraction of a stone, 0.21 × 14 ≈ 3 lb. Converting fractions this way is the same step you'd use to turn decimal feet into inches.
When you'll need stone
UK newspapers, slimming clubs and many British bathroom scales report weight in stone, so a US weight often has to be converted to make sense to a British reader. Someone who weighs 200 lb would describe themselves in the UK as about 14 stone 4.
Clinical settings in the UK record kilograms, so you may need all three units. 200 lb is 90.7 kg. The protein calculator and BMR calculator work from pounds or kilograms, whichever you have to hand.
Frequently asked questions
How many stone is 200 pounds?
200 lb is 14.29 stone, or 14 st 4 lb. Dividing 200 by 14 gives 14 with a remainder of 4. In decimal stone the answer is 14.2857, which scales often round to 14.3. Remember that the 0.3 is a fraction of a stone (about 4 lb), not 3 lb.
Can I convert kilograms straight to stone?
Yes. Divide kilograms by 6.35029318, the exact number of kilograms in a stone. 80 kg is 12.6 st, or 12 st 8 lb. Or convert kilograms to pounds first (multiply by 2.20462) and divide by 14. Both give the same result. The kg to lbs converter's table includes a stone column.
Why does my UK scale show 11.4 st when I weigh 160 lb?
Because 160 ÷ 14 = 11.43 stone, and the scale rounds to one decimal place. In stone and pounds that's 11 st 6 lb. The '.4' is 0.43 of a 14-lb stone, roughly 6 lb, not 4 lb. Switching the scale to st-and-lb mode, if it has one, avoids that confusion.
