Kilograms to Newtons Converter (kg to newton)
Enter a value in kilograms to see it in newtons instantly, or type in the newtons box to convert the other way. 1 kilogram = 9.80665 newtons, and 1 newton (weight) = 0.10197162 kilograms.
Kilograms measure mass and newtons measure force, so this conversion gives the weight of a mass under standard gravity: N = kg × 9.80665. A 60 kg person weighs 588.4 N on Earth, about 97 N on the Moon and 223 N on Mars. Kilogram-force (kgf) is the same idea: 1 kgf = 9.80665 N.
1 kilogram = 9.80665 newtons. Formula: N = kg × 9.80665 (or kg ÷ 0.10197162)

About the kilogram and the newton (weight)
The kilogram is the SI base unit of mass, defined since 2019 in terms of the Planck constant. Body weight, groceries and luggage use kilograms in most of the world.
The newton is the SI unit of force. Weight is a force, so a mass of 1 kg has a weight of 9.80665 N under standard gravity. Kilograms to newtons is a force conversion rather than a mass conversion.
Frequently asked questions
How many newtons are in a kilogram?
There are 9.80665 newtons in 1 kilogram. For any number of kilograms, multiply by 9.80665.
How many kilograms are in a newton (weight)?
1 newton (weight) = 0.10197162 kilograms. To convert newtons to kilograms, multiply by 0.10197162 or divide by 9.80665.
What is 5 kilograms in newtons?
5 kilograms = 49.03325 newtons (5 × 9.80665).
Is the kg to newton conversion exact?
Yes. The 1959 international agreement defined the avoirdupois pound as exactly 0.45359237 kg, so the ounce, stone and ton factors are exact too. Newtons use standard gravity, 9.80665 m/s², which is also an exact defined value. Results are rounded to eight significant digits for display.
