Gram

A gram is a metric mass unit equal to 0.001 kilograms.

Grams are common for food, packaging, recipes, lab samples, parcels, and small goods.

Kilogram

A kilogram is the SI base unit of mass.

Kilograms are used worldwide for commerce, science, food, shipping, equipment, and everyday weights.

How to Convert Gram to Kilogram

Mathematically, kilogram (kg) = gram (g) multiplied by the conversion factor shown below.

1 g = 0.001 kg

1 kg = 1,000 g

1 g x 0.001 = 0.001 kg

The mass in kilogram (kg) is the mass in gram (g) multiplied by 0.001.

mass(kg) = mass(g) x 0.001

Or:

kg = g x 0.001

Formula: value × 0.001

Example: 15 g = 0.015 kg

Example #1

Convert 28.35 gram to kilogram:

28.35 g x 0.001 = 0.02835 kg

Example #2

Convert 250 gram to kilogram:

250 g x 0.001 = 0.25 kg

  1. Start with the mass in grams (g).
  2. Divide by 1000 to convert grams into kilograms.
  3. Use kilograms when the quantity is large enough that a shorter metric weight is easier to read.

Precision note: Use the exact relationship of 1000 grams per kilogram. Preserve decimal kilograms when the gram value is not a whole kilogram.

How many g in kg and kg in g
