How it works
Both units measure weight, so they are always in the same ratio: one kilogram equals 35.273962 ounces. The calculator multiplies the number of kilograms you type by 35.273962 to give ounces, and when you type into the ounces field it divides by the same factor to give kilograms. Because the ratio never changes, doubling the kilograms always doubles the ounces. 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).
