100 kg equals approximately 980.7 newtons.
This conversion is based on multiplying the mass in kilograms by Earth’s gravity (9.807 m/s²). Since weight in newtons is force and mass is in kg, the formula is: weight = mass × gravity.
Conversion Result and Explanation
To convert 100 kg to newtons, multiply 100 by 9.807, which gives 980.7 newtons. This shows the force exerted by Earth’s gravity on an object weighing 100 kg. The calculation reflects how gravity influences mass, transforming it into weight measured in newtons.

Conversion Formula
The conversion formula from kilograms to newtons is: weight (N) = mass (kg) × gravitational acceleration (9.807 m/s²). This works because force is mass times acceleration according to Newton’s second law. For example, 50 kg × 9.807 = 490.35 N.
Conversion Example
- Convert 150 kg:
- Step 1: Identify the mass = 150 kg.
- Step 2: Multiply by gravity: 150 × 9.807.
- Step 3: Calculate: 150 × 9.807 = 1471.05 N.
- Convert 75 kg:
- Step 1: Mass = 75 kg.
- Step 2: 75 × 9.807.
- Step 3: Result is 735.525 N.
- Convert 200 kg:
- Step 1: Mass = 200 kg.
- Step 2: 200 × 9.807.
- Step 3: Equals 1961.4 N.

Conversion Definitions
Kg, or kilogram, is a unit of mass measuring the amount of matter in an object, defined by the International System of Units. It’s used to quantify how much material is present, regardless of location or gravity.
Newtons are units of force in the metric system, representing the push or pull on an object. One newton equals the force needed to accelerate a 1 kg mass at 1 m/s², linking mass and gravitational force.
Conversion FAQs
Why do I multiply kg by 9.807 to get newtons?
This is because force equals mass times acceleration. Earth’s gravity accelerates objects at roughly 9.807 m/s², so multiplying mass by this number yields the weight in newtons.
What happens if I use a different gravity value?
Using a different gravity, such as on the Moon or Mars, changes the weight calculation. For instance, Moon gravity is about 1.622 m/s², so force in newtons would be mass times 1.622 instead of 9.807.
Is a 100 kg object always 980.7 newtons everywhere?
No, because the weight depends on gravity. On Earth, it’s approximately 980.7 N, but on the Moon, it would be about 162.2 N due to lower gravity.
Can I use this conversion for objects in space?
Not directly, because weight in newtons depends on gravitational pull. In space, objects may have mass in kg but experience weightlessness, meaning force in newtons would be near zero without gravity.
