Where does the gram come from?
The gram is a unit of mass in the metric system, equal to one thousandth of a kilogram. It was originally defined in revolutionary France as the mass of one cubic centimeter of pure water at the temperature of melting ice. Today the kilogram (and so the gram) is defined precisely from the Planck constant, removing the need for a physical reference object.
Grams are the standard small-mass unit across most of the world — used everywhere from kitchen scales to laboratory balances, jewelry, and pharmaceuticals.
