How to Convert Gram-force to Newton
- 1 gf = 0.00980665 N
- 1 N = 101.9716213 gf
- Example: convert 15 gf to N: 15 gf = 15 × 0.00980665 N = 0.14709975 N
Formula
N = gf × 0.00980665
or N = gf ÷ 101.9716212978
Derivation from SI units:
- 1 gf = 9.80665 × 10⁻³ N (exact)
- 1 N = 1 kg·m/s²
Both units are defined exactly, so the factor is exact. Gram-force definition: gram-force; Newton definition: newton.
Worked examples
- A reading of 45 gf converts to 0.44129925 N.
45 gf × 0.00980665 = 0.44129925 N - A value of 100 gf is 0.980665 N.
100 gf × 0.00980665 = 0.980665 N
