3. What Are Kilograms?
A kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined as the mass of the International Prototype Kilogram (IPK), a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in Sèvres, France. The kilogram is widely used in science, engineering, and commerce as a standard unit of mass.
3.1 Historical Context of Kilograms
The kilogram was originally defined in the late 18th century as the mass of one liter of water at the temperature of melting ice. However, due to the difficulty of accurately reproducing this definition, the IPK was created in 1889. While the IPK served as the standard for over a century, it was replaced in 2019 with a new definition based on fundamental constants of nature.
3.2 Common Uses of Kilograms
