How to Convert Pound-force to Dyne
- 1 lbf = 444822.1615 dyn
- 1 dyn = 0.000002248089431 lbf
- Example: convert 15 lbf to dyn: 15 lbf = 15 × 444822.1615 dyn = 6672332.423 dyn
Formula
dyn = lbf × 444822.1615261
Derivation from SI units:
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 dyn = 1 g·cm/s² = 10⁻⁵ N
- 1 lbf = 4.448221615261 N ÷ 0.00001 N per dyn = 444822.1615261 dyn
Both units are defined exactly, so the factor is exact. Pound-force definition: pound-force; Dyne definition: dyne.
Worked examples
- A reading of 25 lbf converts to 11120554.04 dyn.
25 lbf × 444822.1615 = 11120554.04 dyn - A value of 500 lbf is 222411080.8 dyn.
500 lbf × 444822.1615 = 222411080.8 dyn
