How to Convert Pound-force to Newtons

To convert a pound-force measurement to a newton measurement, multiply the force by the conversion ratio. One pound-force is equal to 4.448222 newtons, so use this simple formula to convert:

newtons = pound-force × 4.448222

The force in newtons is equal to the pound-force multiplied by 4.448222.

For example, here's how to convert 5 pound-force to newtons using the formula above.
5 lbf = (5 × 4.448222) = 22.241108 N

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

Pound-force

Pound-force is a unit of force equal to the force needed to move one pound of mass at a rate of 32.174049 feet per second squared.

The pound-force is a US customary and imperial unit of force. A pound-force is sometimes also referred to as a pound of force. Pound-force can be abbreviated as lbf, and are also sometimes abbreviated as lbF. For example, 1 pound-force can be written as 1 lbf or 1 lbF.

Pound-force can be expressed using the formula: 1 lbf = 32.174049 lbfts2

Newtons

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 kgms2
