50 kilograms equals approximately 490.5 newtons.
This conversion is based on the fact that weight in newtons is calculated by multiplying mass in kilograms by the acceleration due to gravity, which is approximately 9.81 meters per second squared. So, 50 kg times 9.81 m/s² gives the weight in newtons.
Conversion Result and Explanation
To find how many newtons are in 50 kilograms, you multiply 50 by the gravitational acceleration (9.81 m/s²). This shows the force exerted by gravity on the mass. The result, around 490.5 N, indicates the weight of 50 kg under Earth’s gravity.

Conversion Formula
The formula to convert kilograms to newtons is: weight (N) = mass (kg) × gravity (9.81 m/s²). It works because weight is a force caused by gravity. Multiplying mass by acceleration due to gravity calculates the gravitational force acting on that mass. For example, for 10 kg: 10 × 9.81 = 98.1 N.

Conversion Definitions
Kilograms
Kilograms are units of mass, measuring the amount of matter in an object. It is the base unit of mass in the International System of Units, used worldwide, and distinguishes weight from mass by quantifying the amount of material in an object.
Newtons
Newtons are units of force, representing the push or pull acting on an object. They quantify the gravitational force on a mass, calculated by multiplying mass in kilograms by acceleration due to gravity, approximately 9.81 m/s² on Earth.
Conversion FAQs
Why does multiplying kilograms by 9.81 give newtons?
This is because force in newtons is defined as mass times acceleration. Earth’s gravity accelerates objects at about 9.81 meters per second squared, so multiplying the mass by this value calculates the force exerted by gravity on the object, which is its weight.
Can I use a different gravity value for other planets?
Yes, for planets with different gravitational pulls, replace 9.81 with the local gravity value. For example, Mars has about 3.71 m/s², so multiplying the mass by this value gives the weight on Mars, not Earth.
Is the conversion the same for all objects?
Yes, the formula applies universally, but actual weight varies depending on local gravity. The mass in kilograms remains constant, but the force in newtons depends on the gravitational acceleration at the location.
What happens if I convert a weight in newtons back to kilograms?
To convert force in newtons back to mass in kilograms, divide the force by gravity (9.81). For example, 490.5 N divided by 9.81 gives approximately 50 kg.
