100 kilograms equals 980.665 newtons.
This conversion because weight in newtons is calculated by multiplying mass in kilograms by the acceleration due to gravity, which is approximately 9.80665 m/s². So, 100 kg * 9.80665 m/s² = 980.665 N, giving the force exerted by gravity on the mass.
Conversion Result and Explanation
When converting 100 kilograms into newtons, the resulting force is roughly 980.665 newtons. This represents the weight of the object in Earth’s gravity, calculated by multiplying its mass by the acceleration due to gravity, which is about 9.80665 meters per second squared.

Conversion Formula
The conversion from kilograms to newtons involves multiplying the mass in kilograms by 9.80665, the standard acceleration due to gravity on Earth. For example, if you have 50 kg, the calculation is 50 * 9.80665 = 490.3325 N. This works because weight equals mass times gravity, which is the force exerted by gravity on the object.
Conversion Example
- Convert 20 kg to newtons:
- Step 1: Recognize the formula: weight = mass * gravity.
- Step 2: Substitute 20 kg into the formula: 20 * 9.80665.
- Step 3: Calculate: 20 * 9.80665 = 196.133 N.
- Convert 75 kg to newtons:
- Step 1: Use the same formula.
- Step 2: 75 * 9.80665.
- Step 3: Result is 735.49875 N.
- Convert 150 kg to newtons:
- Step 1: Apply the formula.
- Step 2: 150 * 9.80665.
- Step 3: Calculated as 1470.9975 N.

Conversion Definitions
Kilograms
Kilograms measure mass, indicating how much matter is contained within an object. It is a basic unit in the metric system used worldwide to quantify the amount of material in anything from small particles to large structures.
Newtons
Newtons measure force, specifically the weight exerted by gravity on an object. It describes how strongly gravity pulls on the mass, calculated by multiplying the mass in kilograms by Earth’s acceleration due to gravity, about 9.80665 m/s².
Conversion FAQs
Why is the gravity value 9.80665 used in calculations?
This value is the standard acceleration due to gravity at Earth’s surface, averaged across locations. It provides a consistent basis for converting mass to weight, ensuring calculations are uniform regardless of where on Earth the measurement is taken.
Can I convert kilograms to newtons for objects in space?
Yes, but the gravity differs in space, so you must use the local gravitational acceleration instead of the Earth’s standard 9.80665 m/s². For example, on the Moon, gravity is about 1.625 m/s², so the conversion would be mass times this value instead.
Is the conversion accurate for all Earth locations?
While 9.80665 m/s² is an average, gravity can vary slightly depending on location due to altitude and Earth’s density variations. For precise needs, local gravity measurements should be used, but for most purposes, the standard value is sufficient.
