About the gram and the kilogram

The gram

The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.

The kilogram

The kilogram (kg) is the SI base unit of mass. Since the 2019 redefinition it is defined by fixing the Planck constant to exactly 6.62607015 × 10⁻³⁴ J·s, replacing the old International Prototype Kilogram artifact. In everyday use, the kilogram is the global standard for body weight, groceries, and engineering specifications.
