Both gram (g) and kilogram (kg) are units of mass in the Metric System. So when you convert between these units, you are performing a conversion between two units within the Metric System.

Let's take a closer look at the conversion formulas so that you can do these conversions yourself either with a calculator or with an old-fashioned pencil and paper.

The formula to convert from g to kg is:

kg = g x 0.001

The formula to convert from kg to g is:

g = kg x 1,000

Next, let's look at some examples showing the work and calculations that are involved in converting between grams (g) and kilograms (kg).

Task: Convert 340 grams to kilograms (show work)Formula:g x 0.001 = kgCalculations:340 g x 0.001 = 0.34 kgResult:340 g is equal to 0.34 kg

Task: Convert 2.5 kilograms to grams (show work)Formula:kg x 1,000 = gCalculations:2.5 kg x 1,000 = 2,500 gResult:2.5 kg is equal to 2,500 g

For quick reference purposes, below are conversion tables that you can use to convert from g to kg, and kg to g.
