How to Convert Gram-force to Dyne
- 1 gf = 980.665 dyn
- 1 dyn = 0.001019716213 gf
- Example: convert 15 gf to dyn: 15 gf = 15 × 980.665 dyn = 14709.975 dyn
Formula
dyn = gf × 980.665
Derivation from SI units:
- 1 gf = 9.80665 × 10⁻³ N (exact)
- 1 dyn = 1 g·cm/s² = 10⁻⁵ N
- 1 gf = 0.00980665 N ÷ 0.00001 N per dyn = 980.665 dyn
Both units are defined exactly, so the factor is exact. Gram-force definition: gram-force; Dyne definition: dyne.
Worked examples
- A reading of 45 gf converts to 44129.925 dyn.
45 gf × 980.665 = 44129.925 dyn - A value of 100 gf is 98066.5 dyn.
100 gf × 980.665 = 98066.5 dyn
