How it works
Both units measure weight, so they are always in the same ratio: one stone equals 14 pounds. The calculator multiplies the number of stone you type by 14 to give pounds, and when you type into the pounds field it divides by the same factor to give stone. Because the ratio never changes, doubling the stone always doubles the pounds. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).
