The gram (symbol: g) is the main unit of mass in the Cegesimal System of Units, and the unit of weight in the metric system. It was originally defined as the weight of one cubic centimeter of water at 3.98 °C, and is currently defined as one thousandth of a kilogram, the base unit of mass in the International System of Units.
- 1 g = 0.001 kg = 10−3kg
