### How it works

Both units measure weight, so they are always in the same ratio: one kilogram equals 2.2046226 pounds.

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).
