About Gram to Kilogram
Grams to kilograms is a fundamental metric conversion, with 1,000 grams in every kilogram. It comes up constantly in cooking, shipping, nutrition labels, and science — anywhere a small mass in grams needs to be expressed in kilograms.
To convert grams to kilograms, divide the value in grams by 1,000 (or multiply by 0.001). Kilograms = Grams ÷ 1000.
For example, 500 g ÷ 1000 = 0.5 kg. A 500-gram bag of flour weighs half a kilogram.

A bit of history
The gram was the original base unit of mass in the metric system, but the kilogram became the SI base unit because a 1-gram standard was too small to be practical. The two are simply related by a factor of 1,000.
