About Kilograms to Grams
Convert kilograms to grams instantly, with a reference table of common values. The factor is exact: 1 kg = 1000 g.
A decimal shift used when a bulk weight has to be broken into the gram quantities used in recipes, nutrition labelling and portioning.
The kilogram was the last SI unit defined by a physical object โ a platinum-iridium cylinder held near Paris. In 2019 it was redefined in terms of the Planck constant, ending more than a century of the world's mass standard slowly changing weight relative to its own copies. It is the base SI unit of mass and the standard for body weight, groceries and freight almost everywhere outside the United States. A litre of water weighs almost exactly 1 kg, which is not a coincidence โ the metric system was designed that way.
Worked through with real numbers: 1 kg is 1000 g, 5 kg is 5000 g, 50 kg is 50000 g.
As for the other side of the conversion: A standard paperclip weighs about 1 gram, and a metric cup of flour is roughly 125 g.
Strictly these are conversions of mass rather than weight โ mass is how much matter something contains, weight is the force gravity exerts on it. The distinction rarely matters on Earth, where the two are proportional, but it is why the same object masses the same on the Moon while weighing about a sixth as much.

Frequently asked questions
How do I convert kilograms to grams?
Multiply your kilograms figure by 1000 to get grams โ or type a value above and read the answer straight off.
How many grams are in one kilogram?
1 kg = 1000 g.
When would I need to convert kilograms to grams?
A decimal shift used when a bulk weight has to be broken into the gram quantities used in recipes, nutrition labelling and portioning.
What is a kilogram, exactly?
The kilogram was the last SI unit defined by a physical object โ a platinum-iridium cylinder held near Paris. In 2019 it was redefined in terms of the Planck constant, ending more than a century of the world's mass standard slowly changing weight relative to its own copies. A litre of water weighs almost exactly 1 kg, which is not a coincidence โ the metric system was designed that way.
Where is the gram actually used?
It is the working unit of cooking, nutrition labelling and postage. Baking in grams rather than cups is measurably more accurate, because volume measures of flour vary by how firmly it is packed. A standard paperclip weighs about 1 gram, and a metric cup of flour is roughly 125 g.
Is there anything tricky about weight conversions?
Strictly these are conversions of mass rather than weight โ mass is how much matter something contains, weight is the force gravity exerts on it. The distinction rarely matters on Earth, where the two are proportional, but it is why the same object masses the same on the Moon while weighing about a sixth as much.
Is this converter accurate?
Yes. It uses the exact standard factor of 1 kg = 1000 g, and the conversion runs in your browser so nothing is uploaded.
