## 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:

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.

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 *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 lbfts^{2}

## 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 kgms^{2}
