Convert Pounds-force to Dynes
1 pound-force is 444,822.161526 dyn. One pound-force is exactly 444822.161526 dynes.
One pound-force is 444822.16 dynes. To convert pounds-force to dynes, multiply by 444822.16; to go the other way, divide by 444822.16 or multiply by 2.2481 × 10^-6. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one pound under standard gravity, exactly 4.4482216152605 newtons.

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.
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.
How many dynes are in a pound-force?
One pound-force is 444822.16 dynes. Going the other way, one dyne is 2.2481 × 10^-6 pounds-force. 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.
