kg to g · weight & mass conversion
What are kilograms and grams?
The kilogram is the SI base unit of mass, defined since 2019 by the Planck constant. A gram is one-thousandth of a kilogram, about the mass of a small paperclip. For scale: a 70 kg adult weighs about 154 lb, and a bag of sugar is usually 1 kg (2.2 lb).
How to convert kilograms to grams
1 kg = 1,000 g. To convert, multiply the number of kilograms by 1,000. For example, 5 kg = 5,000 g, and 20 kg = 20,000 g. To go the other way, multiply grams by 0.001 (since 1 g = 0.001 kg).
