Mass represents the amount of matter in an object, a fundamental property that remains constant regardless of location. Unlike weight, which varies with gravity, mass is an intrinsic property of matter. The kilogram (kg) is the SI base unit of mass, used worldwide in science, industry, and commerce.

Milligram

The milligram, one-thousandth of a gram, became important with the rise of pharmaceutical science and precision chemistry. It enables accurate dosing of medications and fine-grained measurement in laboratory settings where very small masses must be controlled and compared.

Gram

Defined during the French Revolution, the gram originally represented the mass of one cubic centimeter of water. It quickly became the cornerstone of the metric system for everyday measurements and remains a fundamental unit in modern science and commerce.

Kilogram

The kilogram is the SI base unit of mass. Once defined by a platinum-iridium artifact, it transitioned in 2019 to a definition based on the Planck constant, linking mass to immutable physical laws instead of physical objects.
