How to convert kilograms to grams?
To convert a measurement in kilograms (kg) to grams (g), we multiply the value by the conversion factor 1000.
g = kg × 1,000.00
The kilogram is the base unit of mass in the International System. Since 2019, it's no longer defined by a physical reference object (the former platinum-iridium cylinder in Paris), but by a fundamental physical constant, the Planck constant.
| Kilograms (kg) | Grams (g) |

Frequently Asked Questions
How many grams are in 1 kilogram?
1 kg equals exactly 1000 grams.
Is the platinum cylinder in Paris still used to define the kilogram?
No. Since May 2019, the kilogram has been redefined based on the Planck constant, a fixed physical value, so that it no longer depends on any physical object that could wear down or change.
