How to Convert Kilogram-Force to Newtons

To convert a measurement in kilogram-force to a measurement in newtons, multiply the force by the following conversion ratio: 9.80665 newtons/kilogram-force.

Since one kilogram-force is equal to 9.80665 newtons, you can use this simple formula to convert:

newtons = kilogram-force × 9.80665

The force in newtons is equal to the force in kilogram-force multiplied by 9.80665.

For example, here's how to convert 5 kilogram-force to newtons using the formula above.

newtons = (5 kgf × 9.80665) = 49.033251 N

How Many Newtons Are in One Kilogram-Force?

There are 9.80665 newtons in one kilogram-force, which is why we use this value in the formula above.

1 kgf = 9.80665 N

Kilogram-force and newtons are both units used to measure force. Keep reading to learn more about each unit of measure.

What Is Kilogram-Force?

Kilogram-force is a unit of force equal to the force needed to move one kilogram of mass at a rate of 9.80665 meters per second squared.

The kilogram-force is a non-SI metric unit for force. Kilogram-force is sometimes also referred to as a kilopond. Kilogram-force can be abbreviated as kgf, and are also sometimes abbreviated as kg_F. For example, 1 kilogram-force can be written as 1 kgf or 1 kg_F.

Kilogram-force can be expressed using the formula: 1 kgf = 9.80665 kgm / s²

What Is a Newton?

The newton is a unit to for measuring force equal to the force needed to move one kilogram of mass at a rate of one meter per second squared.^[1]

The newton is the SI derived unit for force in the metric system. Newtons can be abbreviated as N; for example, 1 newton can be written as 1 N.

Newtons can be expressed using the formula: 1 N = 1 kgm / s²
