How it works
Both units measure weight, so they are always in the same ratio: one kilogram equals 2.2046226 pounds. The calculator multiplies the number of kilograms you type by 2.2046226 to give pounds, and when you type into the pounds field it divides by the same factor to give kilograms. Because the ratio never changes, doubling the kilograms 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).
