How to Convert Pound-force to Ounce-force
- 1 lbf = 16 ozf
- 1 ozf = 0.0625 lbf
- Example: convert 15 lbf to ozf: 15 lbf = 15 × 16 ozf = 240 ozf
Formula
ozf = lbf × 16
Derivation from SI units:
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 ozf = 1/16 lbf = 0.27801385095378 N
- 1 lbf = 4.448221615261 N ÷ 0.2780138509538 N per ozf = 16 ozf
Both units are defined exactly, so the factor is exact. Pound-force definition: pound-force; Ounce-force definition: ounce-force.
Worked examples
- A reading of 25 lbf converts to 400 ozf.
25 lbf × 16 = 400 ozf - A value of 500 lbf is 8000 ozf.
500 lbf × 16 = 8000 ozf
