History

The history of the kilogram dates back to the late 18th century during the French Revolution when the metric system was established. Initially, a kilogram was defined as the mass of one liter of water.

Later, it was refined into a physical object known as IPK (International Prototype of the Kilogram), a platinum-iridium alloy cylinder kept at the BIPM in France.

However, relying on a physical prototype posed challenges due to its susceptibility to change over time. To address this, in 2019, the kilogram underwent a significant redefinition based on a fundamental constant of nature known as the Planck constant.

Use

Kilogram is used on food packaging, gym equipment, a weight converter, and many other items where weight is indicated.
