How to convert grams to kilograms

kilograms = grams × 0.001

The gram is the metric everyday unit for cooking ingredients, letters and jewelry. Originally defined as the mass of a cubic centimeter of water.

The kilogram is the SI base unit of mass, since 2019 defined via the Planck constant rather than a physical metal cylinder in Paris.
