Convert Dynes to Pounds-force
1 dyne is 0.000002 lbf. One dyne is exactly 0.000002248089431 pounds-force.
One dyne is 2.2481 × 10^-6 pounds-force. To convert dynes to pounds-force, multiply by 2.2481 × 10^-6; to go the other way, divide by 2.2481 × 10^-6 or multiply by 444822.16. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly a hundred-thousandth of a newton, from the older centimetre-gram-second system.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert dynes to pounds-force?
- 1.Take the measurement in dynes.
- 2.Multiply by 2.2481 × 10^-6 — that is how many pounds-force fit in one dyne.
- 3.To go back the other way, divide by 2.2481 × 10^-6, or multiply by 444822.16.
Worked example: 25 dynes to pounds-force
- Formula
- dyn × 2.2481 × 10^-6 = lbf
- Arithmetic
- 25 × 2.2481 × 10^-6 = 0.000056 lbf
- Answer
- 25 dyn = 0.000056 lbf
The factor is rounded for display; the figure above is computed from the full value.

What is a dyne?
Exactly a hundred-thousandth of a newton, from the older centimetre-gram-second system. Surface tension and older physics texts still use it.
What is a pound-force?
The weight of one pound under standard gravity, exactly 4.4482216152605 newtons. A pound of mass and a pound-force are different quantities that share a name, which is why this unit exists at all.
How many pounds-force are in a dyne?
One dyne is 2.2481 × 10^-6 pounds-force. Going the other way, one pound-force is 444822.16 dynes. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
