What is a kilogram and how is it defined?

A kilogram (kg) is the SI base unit of mass, quantifying the amount of matter in an object. It is defined since 2019 by fixing the Planck constant.

When should I use gigagrams instead of kilograms?

Gigagrams are best used for expressing very large masses, such as bulk commodities, greenhouse-gas emissions, or large stockpiles, typically when dealing with hundreds of thousands of kilograms or more.

Can I convert small masses from kilograms to gigagrams?

While possible, converting small masses to gigagrams may result in very small decimal values that are less intuitive and harder to interpret.
