115 kg equals approximately 1134.5 newtons.
Converting kilograms to newtons involves multiplying the mass in kg by the acceleration due to gravity, which is roughly 9.81 m/s². So, 115 kg multiplied by 9.81 gives the force in newtons, representing the weight of the object under Earth’s gravity.

Conversion Formula
The conversion from kilograms to newtons uses the formula: Force (N) = mass (kg) × acceleration due to gravity (m/s²). Since gravity on Earth averages about 9.81 m/s², multiplying mass in kg by this value gives the weight in newtons. For example, 115 kg × 9.81 = 1134.15 N.
Conversion Example
- Convert 50 kg to newtons:
- Multiply 50 by 9.81
- 50 × 9.81 = 490.5 N
- Thus, 50 kg weighs approximately 490.5 newtons.
- Convert 200 kg to newtons:
- Multiply 200 by 9.81
- 200 × 9.81 = 1962 N
- So, 200 kg equals around 1962 newtons.
- Convert 75 kg to newtons:
- 75 × 9.81 = 735.75 N
- Meaning, 75 kg exerts approximately 735.75 newtons of force.
- Convert 120 kg:
- 120 × 9.81 = 1177.2 N
- Therefore, 120 kg is about 1177.2 newtons.

Conversion Definitions
kg
Kg, or kilogram, is a metric unit of mass, representing the amount of matter in an object. It is the base unit of mass in the International System of Units (SI), and one kilogram is equal to 1000 grams.
newtons
Newtons are units of force in the SI system, measuring the push or pull on an object. One newton equals the force required to accelerate a one-kilogram mass at a rate of 1 meter per second squared.
Conversion FAQs
Why does multiplying kg by 9.81 give the force in newtons?
This multiplication works because gravity exerts an acceleration of approximately 9.81 m/s² on objects near Earth’s surface. Force equals mass times acceleration, so multiplying the mass by this acceleration yields the weight in newtons.
Is the 9.81 m/s² value exact for all locations on Earth?
No, gravity varies slightly depending on location, altitude, and Earth’s shape. The 9.81 m/s² is an average value used for most calculations, but precise measurements may differ slightly, especially in high-altitude or polar regions.
Can I convert kilograms to newtons without considering gravity?
No, because newtons measure force resulting from gravity acting on mass. Without accounting for gravity, you only have mass in kilograms, which does not directly translate to force without the acceleration factor.
Does the conversion change on different planets?
Yes, because gravity varies across planets. To find the force in newtons on another planet, multiply the mass in kg by that planet’s gravitational acceleration, which can differ significantly from Earth’s 9.81 m/s².
Is this conversion only for weight measurement?
Primarily, yes. The force in newtons calculated from kg represents the weight or gravitational force acting on the object. It does not measure mass directly, which remains constant regardless of location.
