Convert Pounds-force to Ounces-force
1 pound-force is 16 ozf. One pound-force is exactly 16 ounces-force.
One pound-force is 16 ounces-force. To convert pounds-force to ounces-force, multiply by 16; to go the other way, divide by 16 or multiply by 0.0625. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one pound under standard gravity, exactly 4.4482216152605 newtons.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert pounds-force to ounces-force?
- 1.Take the measurement in pounds-force.
- 2.Multiply by 16 — that is how many ounces-force fit in one pound-force.
- 3.To go back the other way, divide by 16, or multiply by 0.0625.
Worked example: 25 pounds-force to ounces-force
- Formula
- lbf × 16 = ozf
- Arithmetic
- 25 × 16 = 400 ozf
- Answer
- 25 lbf = 400 ozf
The factor is exact, so this figure is exact too — only the display is rounded.

What is a pound-force?
The weight of one pound under standard gravity, exactly 4.4482216152605 newtons. A pound of mass and a pound-force are different quantities that share a name, which is why this unit exists at all.
What is an ounce-force?
A sixteenth of a pound-force. Spring tensions, switch actuation and small-motor specifications are given here.
How many ounces-force are in a pound-force?
One pound-force is 16 ounces-force, exactly. Going the other way, one ounce-force is 0.0625 pounds-force. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
