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

What is a grain used for?

The grain (gr) is a traditional mass unit used mainly for bullet weights, archery arrows, and historical pharmaceutical dosages.

Why convert kilograms to grains?

Converting kilograms to grains helps express very small masses precisely in contexts like ballistics and traditional pharmacy where grains remain standard.
