Facts about the Gram
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is commonly used in cooking, grocery shopping, nutrition labels, and scientific contexts for measuring lighter objects. The gram originated during the French Revolution as part of the original metric system.
Facts about the Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI). Defined originally as the mass of a liter of water, it was later represented by a platinum-iridium prototype kept in France. In 2019, it was redefined using Planck's constant, linking mass to a fundamental constant of nature. Kilograms are widely used for weighing groceries, people, and cargo worldwide.
