How to Convert Ounce-force to Gram-force
- 1 ozf = 28.34952313 gf
- 1 gf = 0.03527396195 ozf
- Example: convert 15 ozf to gf: 15 ozf = 15 × 28.34952313 gf = 425.2428469 gf
Formula
gf = ozf × 28.349523125
Derivation from SI units:
- 1 ozf = 1/16 lbf = 0.27801385095378 N
- 1 gf = 9.80665 × 10⁻³ N (exact)
- 1 ozf = 0.2780138509538 N ÷ 0.00980665 N per gf = 28.349523125 gf
Both units are defined exactly, so the factor is exact. Ounce-force definition: ounce-force; Gram-force definition: gram-force.
Worked examples
- A reading of 4 ozf converts to 113.3980925 gf.
4 ozf × 28.34952313 = 113.3980925 gf - A value of 16 ozf is 453.59237 gf.
16 ozf × 28.34952313 = 453.59237 gf
