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.

How do you convert pounds-force to dynes?

  1. 1.Take the measurement in pounds-force.
  2. 2.Multiply by 444822.16 — that is how many dynes fit in one pound-force.
  3. 3.To go back the other way, divide by 444822.16, or multiply by 2.2481 × 10^-6.

Worked example: 25 pounds-force to dynes

Formula
lbf × 444822.16 = dyn
Arithmetic

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.
