Understanding grams and kilograms

To convert grams to kilograms, divide by 1,000. A value below 1,000 grams becomes a value below one kilogram.

What are grams (g)?

A gram (g) is a metric unit of mass equal to one thousandth of a kilogram. Food ingredients and small packages are often measured in grams.

What are kilograms (kg)?

A kilogram (kg) is the SI base unit of mass. The prefix kilo means 1,000, so one kilogram contains 1,000 grams.

How to use this converter

  1. Enter the mass in grams.
  2. Read the equivalent number of kilograms.
  3. Include a leading zero for values below one, such as 0.75 kg.

The conversion formula

kilograms = grams ÷ 1,000

A worked example

A 750 g bag has a mass of 750 ÷ 1,000 = 0.75 kg, or three quarters of a kilogram.

Compare a 750 g packet with a 1 kg packet by expressing both in kilograms. The smaller packet is 0.75 kg, which is 0.25 kg less.
