Gram to Kilogram Converter (g to kg)
Instantly convert between grams and kilograms using this precise tool. Essential for cooking, scientific research, and industrial applications. 100% free with no registration required.
Conversion Formula
1 gram (g) = 0.001 kilograms (kg)
To convert grams to kilograms:
kilograms = grams ÷ 1000
Example: 2500 g ÷ 1000 = 2.5 kg

Definition and Background
What is a Gram?
A gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. The name comes from:
- Latin “gramma”: meaning small weight
- Part of the metric system established during the French Revolution
What is a Kilogram?
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It was originally defined in 1795 as:
- The mass of one liter of water at 4°C
- Now defined by the Planck constant (since 2019)
Metric System Hierarchy
| Unit | Symbol | Kilograms |
|---|---|---|
| Milligram | mg | 0.000001 kg |
| Gram | g | 0.001 kg |
| Kilogram | kg | 1 kg |
| Hectogram | hg | 0.1 kg |
| Tonne | t | 1000 kg |
Frequently Asked Questions
Why would I use grams instead of kilograms?
Grams are ideal for measuring small quantities where precision is needed, such as in cooking or laboratory settings.
How precise is gram measurement?
Grams offer high precision for small masses (1 g = 0.001 kg), making them suitable for applications requiring exact measurements.
What’s the history of the gram?
Introduced during the French Revolution as part of the metric system, derived from the Latin “gramma” (small weight).
Are grams used worldwide?
Grams are widely used globally in countries adopting the metric system, though ounces are more common in the US for some applications.
