what is a gram

A gram is a unit of mass in the International System of Units (SI), equal to one one-thousandth of a kilogram. It is the most widely used unit of measurement for non-liquid ingredients in cooking and grocery shopping worldwide. The gram is a mass measurement, not a weight. Mass is the measurement of the amount of matter an object contains, while weight is the gravitational pull the Earth has on an object. The official SI symbol for gram is "g".
