One of the most commonly used units of measurements in the world is the gram. As you know, it is the SI base unit of mass, but also is a measurement commonly used in medicine, science, cooking, baking, etc. Converting from grams to kilogram is a simple process that involves only simple mathematical steps.

How do you convert G to KG formula?
The international system of units (SI) is the modern form of the metric system, and is the most widely used system of measurement. The SI is a coherent system of units of measurement built on seven base units.
When using the standard imperial units, the SI is often referred to as the meter-kilogram-second (MKS) system of units.
The seven SI base units are the meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), candela (luminous intensity), and mole (amount of substance).
The formula of G to KG is: Gram value x 0.001
OR, Gram Value ÷ 1000
How Many KG in a Gram Conversion
Grams and kilograms are both units of measurement for weight, but they’re not interchangeable. A gram is defined as 1/1,000 of a kilogram, which is the SI unit of mass. (SI stands for “International System of Units,” which is the modern term for the metric system.)
By contrast, a kilogram is equal to 2.2 pounds, or more accurately, 453.59237 grams.
