How it works
Every unit converts to grams first using exact definitions (1 kg = 1000 g, 1 lb = 453.59237 g, 1 oz = 1⁄16 lb = 28.349523125 g, 1 stone = 14 lb = 6350.29318 g), then from grams to the target unit. Converting through a common base unit keeps every conversion pair exact.
This treats mass units interchangeably (kilograms and pounds), which is the everyday meaning of 'weight' at Earth's surface — it isn't a physics force conversion.
