How to Convert Pound-Force to Newtons
To convert a measurement in pound-force to a measurement in newtons, multiply the force by the following conversion ratio: 4.448222 newtons/pound-force.
Since one pound-force is equal to 4.448222 newtons, you can use this simple formula to convert:
newtons = pound-force × 4.448222
The force in newtons is equal to the force in pound-force multiplied by 4.448222.
For example, here's how to convert 5 pound-force to newtons using the formula above.
newtons = (5 lbf × 4.448222) = 22.241108 N
How Many Newtons Are in One Pound-Force?
There are 4.448222 newtons in one pound-force, which is why we use this value in the formula above.
1 lbf = 4.448222 N
Pound-force and newtons are both units used to measure force. Keep reading to learn more about each unit of measure.
What Is 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. 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 lbft / 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
