How to Convert Ounce-force to Kilogram-force
- 1 ozf = 0.02834952313 kgf
- 1 kgf = 35.27396195 ozf
- Example: convert 15 ozf to kgf: 15 ozf = 15 × 0.02834952313 kgf = 0.4252428469 kgf
Formula
kgf = ozf × 0.028349523125
or kgf = ozf ÷ 35.27396194958
Derivation from SI units:
- 1 ozf = 1/16 lbf = 0.27801385095378 N
- 1 kgf = 1 kg × 9.80665 m/s² = 9.80665 N (exact)
- 1 ozf = 0.2780138509538 N ÷ 9.80665 N per kgf = 0.028349523125 kgf
Both units are defined exactly, so the factor is exact. Ounce-force definition: ounce-force; Kilogram-force definition: kilogram-force.
Worked examples
- A reading of 4 ozf converts to 0.1133980925 kgf.
4 ozf × 0.02834952313 = 0.1133980925 kgf - A value of 16 ozf is 0.45359237 kgf.
16 ozf × 0.02834952313 = 0.45359237 kgf
