Convert Kilograms-force to Dynes
1 kilogram-force is 980,665 dyn. One kilogram-force is exactly 980665 dynes.
One kilogram-force is 980665 dynes. To convert kilograms-force to dynes, multiply by 980665; to go the other way, divide by 980665 or multiply by 1.0197 × 10^-6. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity.

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 kilograms-force to dynes?
- 1.Take the measurement in kilograms-force.
- 2.Multiply by 980665 — that is how many dynes fit in one kilogram-force.
- 3.To go back the other way, divide by 980665, or multiply by 1.0197 × 10^-6.
Worked example: 25 kilograms-force to dynes
- Formula
- kgf × 980665 = dyn
- Arithmetic
- 25 × 980665 = 24,516,625 dyn
- Answer
- 25 kgf = 24,516,625 dyn
The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilogram-force?
The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity. Older European engineering drawings are full of it.
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 kilogram-force?
One kilogram-force is 980665 dynes, exactly. Going the other way, one dyne is 1.0197 × 10^-6 kilograms-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.
