How does the Weight Converter work?
A weight converter changes a mass from one unit to another, such as pounds to kilograms. Values go through kilograms: result = value × (kg per from-unit) / (kg per to-unit).
The factors are exact: 1 lb = 0.45359237 kg, 1 oz = 28.349523125 g, and a US (short) ton is 2,000 lb. For example, 150 lb is 150 × 0.45359237 = 68.04 kg.
