If you’re working in physics, engineering, or mechanics, converting force (in Newtons) to mass (in kilograms) is a routine yet vital task. The N to Mass Calculator simplifies this conversion by instantly computing the mass based on the force you input in Newtons (N).
This free online tool allows you to skip the manual calculations and instantly convert Newtons to kilograms using the universally accepted relation derived from Newton’s Second Law of Motion. Whether you’re a student, teacher, or engineer, this calculator ensures accuracy and saves you time.
What is a Newton?
Before diving into the mass calculation, it’s important to understand what a Newton is. A Newton (N) is a unit of force in the International System of Units (SI).
One Newton is defined as the force required to accelerate a 1 kilogram mass by 1 meter per second squared (1 m/s²).
So,
1 N = 1 kg × 1 m/s²
Formula to Convert N to Mass
The relationship between force, mass, and acceleration is given by Newton’s Second Law of Motion:
Force = Mass × Acceleration
This can be rearranged to calculate mass:
Mass = Force / Acceleration
In this context:
- Force is measured in Newtons (N)
- Mass is measured in kilograms (kg)
- Acceleration is typically the acceleration due to gravity, which is 9.81 m/s² on Earth
Final Formula Used in the Calculator:
Mass (kg) = N / 9.81

20 Frequently Asked Questions (FAQs)
1. What is 1 Newton in mass?
1 Newton is equal to approximately 0.102 kilograms on Earth.
2. How is mass different from force?
Mass is the amount of matter in an object (kg), while force is a push or pull on that object (N).
3. Why divide by 9.81 to convert Newtons to mass?
Because force equals mass times acceleration (F = m × a), and on Earth, a = 9.81 m/s².
4. Can I use this calculator for space applications?
No, this calculator assumes Earth’s gravity. For space or other planets, use the correct acceleration value.
5. What is the unit of mass?
Kilograms (kg).
6. What is the unit of force?
Newtons (N).
7. Is 9.81 always the value for gravity?
It’s an average. Gravity slightly varies depending on location, but 9.81 m/s² is commonly used.
8. What is the mass of a 500 N force?
Mass = 500 / 9.81 = 50.97 kg
