How to Convert Ounce-Force to Newtons

To convert a measurement in ounce-force to a measurement in newtons, multiply the force by the following conversion ratio: 0.278014 newtons/ounce-force.

Since one ounce-force is equal to 0.278014 newtons, you can use this simple formula to convert:

newtons = ounce-force × 0.278014

The force in newtons is equal to the force in ounce-force multiplied by 0.278014.

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

newtons = (5 ozf × 0.278014) = 1.390069 N

How Many Newtons Are in One Ounce-Force?

There are 0.278014 newtons in one ounce-force, which is why we use this value in the formula above.

1 ozf = 0.278014 N

What Is Ounce-Force?

Ounce-force is a unit of force equal to the force needed to move one ounce of mass at a rate of 32.174049 feet per second squared. One ounce of force is equal to 1/16th of a pound of force.

The ounce-force is a US customary and imperial unit of force. Ounce-force can be abbreviated as ozf, and are also sometimes abbreviated as oz_F. For example, 1 ounce-force can be written as 1 ozf or 1 oz_F.

Ounce-force can be expressed using the formula: 1 ozf = 32.174049 ozft / 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
