How to Convert Pound-Force to Kilonewtons

To convert a measurement in pound-force to a measurement in kilonewtons, multiply the force by the following conversion ratio: 0.004448 kilonewtons/pound-force.

Since one pound-force is equal to 0.004448 kilonewtons, you can use this simple formula to convert:

kilonewtons = pound-force × 0.004448

The force in kilonewtons is equal to the force in pound-force multiplied by 0.004448.

For example, here's how to convert 500 pound-force to kilonewtons using the formula above.

kilonewtons = (500 lbf × 0.004448) = 2.224111 kN

Pound-force and kilonewtons 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 lb_F. For example, 1 pound-force can be written as 1 lbf or 1 lb_F.

Pound-force can be expressed using the formula: 1 lbf = 32.174049 lbft / s²

What Is a Kilonewton?

One kilonewton is equal to 1,000 newtons, which are equal to the force needed to move one kilogram of mass at a rate of one meter per second squared.

The kilonewton is a multiple of the newton, which is the SI derived unit for force. In the metric system, "kilo" is the prefix for thousands, or 10³. Kilonewtons can be abbreviated as kN; for example, 1 kilonewton can be written as 1 kN.
