How to Convert Dyne to Pound-force
- 1 dyn = 0.000002248089431 lbf
- 1 lbf = 444822.1615 dyn
- Example: convert 15 dyn to lbf: 15 dyn = 15 × 0.000002248089431 lbf = 0.00003372134146 lbf
Formula
lbf = dyn × 0.000002248089430997
or lbf = dyn ÷ 444822.1615261
Derivation from SI units:
- 1 dyn = 1 g·cm/s² = 10⁻⁵ N
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 dyn = 0.00001 N ÷ 4.448221615261 N per lbf = 0.000002248089430997 lbf
Both units are defined exactly, so the factor is exact. Dyne definition: dyne; Pound-force definition: pound-force.
Worked examples
- A reading of 100 dyn converts to 0.0002248089431 lbf.
100 dyn × 0.000002248089431 = 0.0002248089431 lbf - A value of 100000 dyn is 0.2248089431 lbf.
100000 dyn × 0.000002248089431 = 0.2248089431 lbf
