This conversion works because newtons measure force, and kilograms measure mass. By dividing the force (in newtons) by the acceleration due to gravity (9.8 m/s²), you get the mass in kilograms that would produce that force under Earth’s gravity.

Conversion Formula
The formula to convert newtons (n) to kilograms (kg) is:
mass (kg) = force (N) ÷ acceleration due to gravity (9.8 m/s²)
This works because newtons measure force, which is mass times acceleration (F = m × a). Earth’s gravity causes an acceleration of approximately 9.8 m/s². So, dividing the force by 9.8 gives the mass responsible for that force.
Example calculation:
- Force = 9.8 N
- Acceleration due to gravity = 9.8 m/s²
- Mass = 9.8 N ÷ 9.8 m/s² = 1 kg
Conversion Example
- Convert 19.6 N to kg:
- Divide 19.6 by 9.8.
- 19.6 ÷ 9.8 = 2 kg.
- This means a force of 19.6 newtons corresponds to 2 kilograms of mass under Earth’s gravity.
- Convert 4.9 N to kg:
- 4.9 ÷ 9.8 = 0.5 kg.
- So, 4.9 newtons is the force exerted by 0.5 kg mass.
- Convert 29.4 N to kg:
- 29.4 ÷ 9.8 = 3 kg.
- This shows 29.4 newtons corresponds to 3 kilograms of mass.
- Convert 0 N to kg:
- 0 ÷ 9.8 = 0 kg.
- No force means no mass causing it.
- Convert 49 N to kg:
- 49 ÷ 9.8 = 5 kg.
- Force of 49 newtons results from 5 kilograms.

Conversion Definitions
n (newton): A newton is the SI unit of force, symbolized by N, defined as the force needed to accelerate a 1-kilogram mass by 1 meter per second squared. It quantifies the push or pull on an object, incorporating mass and acceleration in its measure.
kg (kilogram): Kilogram, abbreviated as kg, is the base unit of mass in the International System of Units. One kilogram represents the mass of the international prototype kilogram, used worldwide for measuring the amount of matter in an object.
Conversion FAQs
Does converting newtons to kilograms depend on location?
The conversion depends on the acceleration due to gravity, which can vary slightly on Earth’s surface. The standard 9.8 m/s² is an average, so the mass calculated from force in newtons assumes this average gravity. Different planets or altitudes change the acceleration, affecting the conversion.
Can I convert newtons to kilograms without using gravity?
No, because newtons measure force, which includes acceleration. Without specifying acceleration, converting force to mass is impossible. The 9.8 m/s² gravity value links force and mass on Earth, so it’s necessary for the conversion.
Why is 9.8 newtons equal to 1 kilogram mass exactly?
Because of Earth’s gravity acceleration of about 9.8 m/s², a mass of 1 kilogram experiences a gravitational force of 9.8 newtons. This relationship sets the conversion ratio used in force-to-mass calculations on Earth.
What if I want to convert force in newtons to mass in pounds?
You first convert newtons to kilograms by dividing by 9.8, then convert kilograms to pounds using the factor 2.20462. This two-step process is necessary because pounds measure mass, but newtons measure force.
Is the conversion from newtons to kilograms exact or approximate?
The conversion is approximate because Earth’s gravity varies slightly across locations, and 9.8 m/s² is a rounded value. For most practical purposes, this approximation is accurate enough, but high-precision work may require adjusted gravity values.
