公式
Result = (value × from-factor) ÷ to-factor, relative to the gram
Every weight unit has a fixed, exact conversion factor to grams: 1 kilogram = 1,000 g, 1 ounce = 28.349523125 g, 1 pound = 453.59237 g and 1 stone = 6,350.29318 g (i.e. 14 pounds). The calculator converts your value to grams first as an intermediate step and then to the target unit, so every combination is exact.
