How many kilogram-force is one dyne?

Exactly 1.01971621 × 10⁻⁶ kgf. One kilogram-force equals 980,665 dynes (standard gravity in cm/s² × 1000), so 1 dyne = 1/980,665 kgf ≈ 1.01972 × 10⁻⁶ kgf.

A dyne (dyn) is the CGS unit of force. It is defined as the force needed to accelerate 1 gram of mass at 1 cm/s². It is a very small unit — it takes 980,665 dynes to equal just 1 kilogram-force.

What is a kilogram-force?

A kilogram-force (kgf), also called kilopond (kp), is the force exerted by a mass of one kilogram under standard gravitational acceleration (9.80665 m/s²). It is commonly used in mechanical engineering and in older European technical standards.

Is the conversion exact?

Yes. Standard gravity is defined as exactly 9.80665 m/s² = 980.665 cm/s², so 1 kgf = 1000 g × 980.665 cm/s² = 980,665 dyn. The factor 980,665 is exact by definition.

Can I convert kilogram-force back to dynes?

Yes. To convert kgf to dynes, multiply by 980,665. Use the swap button in the converter to reverse the direction instantly.
