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.
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.
