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 = kg Calculations: 340 g x 0.001 = 0.34 kg Result: 340 g is equal to 0.34 kg
Task: Convert 2.5 kilograms to grams (show work) Formula: kg x 1,000 = g Calculations: 2.5 kg x 1,000 = 2,500 g Result: 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.
