50 kilograms equals 490.5 newtons
To convert 50 kilograms to newtons, multiply by 9.81, which is the acceleration due to gravity. The result is 490.5 newtons. This means the weight of an object with 50 kg mass under Earth’s gravity is about 490.5 N.
The conversion from kilograms to newtons works because kilograms measure mass, and newtons measure force. Force due to gravity on an object equals its mass times the acceleration due to gravity (approximately 9.81 m/s²). So, multiplying 50 kg by 9.81 gives the weight in newtons.

Conversion Formula
The formula to convert kilograms to newtons is force (N) = mass (kg) × gravity (9.81 m/s²). This works because gravity exerts a force on every mass, and multiplying the mass by the acceleration of gravity gives the weight. For example, 10 kg × 9.81 = 98.1 N.
Conversion Example
- Convert 10 kg to newtons:
- Multiply 10 kg by 9.81 m/s²
- 10 × 9.81 = 98.1 N
- Convert 25 kg to newtons:
- Multiply 25 kg by 9.81 m/s²
- 25 × 9.81 = 245.25 N
- Convert 75 kg to newtons:
- Multiply 75 kg by 9.81 m/s²
- 75 × 9.81 = 735.75 N

Conversion Definitions
Kilograms
Kilograms are units of mass measuring the amount of matter in an object, used globally in the metric system, symbolized as kg. One kilogram equals 1000 grams and is a standard measure for weight and mass in scientific contexts.
Newtons
Newtons are units of force, representing the push or pull on an object, defined as the force needed to accelerate a 1 kg mass at 1 meter per second squared. It measures weight under gravity, symbolized as N, used in physics and engineering calculations.
Conversion FAQs
Why do I need to multiply by 9.81 to convert kg to newtons?
This is because 9.81 m/s² is Earth’s average acceleration due to gravity. Multiplying mass in kilograms by gravity gives the force in newtons, which is the weight of an object under Earth’s gravity.
Can I convert kilograms to newtons for objects in space?
Yes, but the conversion depends on the gravity of the location. Since gravity varies across planets and moons, multiply the mass by the local gravity (not 9.81 m/s²) to get the force in newtons.
What is the importance of understanding the difference between mass and weight?
Mass measures matter’s quantity, while weight measures force due to gravity acting on that mass. Knowing this helps in precise calculations for physics experiments, engineering, and understanding how objects behave in different gravitational fields.
