100 kg converts to approximately 980.7 newtons.
This conversion is based on the fact that 1 kilogram exerts a force of about 9.807 newtons due to gravity. So, multiplying 100 kg by 9.807 gives the force in newtons, which is how weight or force caused by gravity is calculated from mass.
Conversion Result and Explanation
To convert 100 kg to newtons, we multiply the mass value by the acceleration due to gravity (roughly 9.807 m/s²). This is because weight is the force exerted by gravity on an object, and force equals mass times acceleration. Therefore, 100 kg times 9.807 m/s² results in approximately 980.7 newtons.

Conversion Formula
The formula to convert kilograms to newtons involves multiplying the mass in kg by the acceleration due to gravity, which is approximately 9.807 m/s². Weight (N) = mass (kg) × gravity (m/s²). This works because force equals mass times acceleration according to Newton’s second law.
For example, if you have 50 kg, multiply 50 by 9.807: 50 × 9.807 = 490.35 N. This calculation shows how much force gravity exerts on that mass, making it a straightforward way to determine weight in newtons.
Conversion Example
- Convert 75 kg to newtons:
- Step 1: Write down the mass: 75 kg.
- Step 2: Multiply by 9.807: 75 × 9.807 = 735.525 N.
- Step 3: Result: 75 kg equals approximately 735.525 newtons.
- Convert 150 kg to newtons:
- Step 1: Mass is 150 kg.
- Step 2: Multiply by 9.807: 150 × 9.807 = 1470.45 N.
- Step 3: Force exerted is about 1470.45 newtons.
- Convert 200 kg to newtons:
- Step 1: Mass in kg: 200.
- Step 2: Multiply: 200 × 9.807 = 1961.4 N.
- Step 3: Result: about 1961.4 newtons.

Conversion Definitions
kg: A kilogram is a unit of mass that measures the amount of matter in an object, used internationally, and is part of the metric system. It is defined by a platinum-iridium alloy cylinder stored in France. It does not change with gravity or location.
Newtons: Newtons is a force unit in the metric system, representing the pull or weight that gravity exerts on a mass. One newton equals the force needed to accelerate a one kilogram mass at 1 meter per second squared, reflecting gravity’s influence.
Conversion FAQs
How accurate is the 9.807 m/s² value for gravity in these calculations?
The 9.807 m/s² value is an average gravity on Earth’s surface at sea level. Variations occur due to location, altitude, and local density of Earth’s crust, so calculations might slightly differ depending on precise conditions, but it’s generally accurate enough for most purposes.
Can I convert other units of mass to newtons using this method?
Yes, but only if the mass is expressed in kilograms. If you have mass in pounds, grams, or other units, you first need to convert to kilograms before multiplying by 9.807 to get the force in newtons. Conversion factors are available for these units.
What happens if I use a different gravity value?
Using a different gravity value affects the result proportionally. For example, on the Moon, gravity is about 1.622 m/s², so the force for 100 kg would be 100 × 1.622 = 162.2 N. Always use the appropriate gravity value for the location you are calculating for.
