Key Formulas

Formula

lb = st × (6.35029318 / 0.45359237)

One stone is 14 pounds, so multiply stone by 14. NIST Handbook 44 gives 14 avoirdupois pounds per stone, and NIST footnote 22 defines the pound behind the rest of the weight set. Someone reading a UK scale in stone and a US scale in pounds uses this pair to compare the two. 9 st is 126 lb. Add leftover pounds after multiplying, so 9 st 3 lb is 129 lb.
