About Converting Dynes to Kilogram-forces
Dyne and Kilogram-force both measure force, and the conversion matters whenever an SI-trained engineer needs to compare notes with a US-trained one, or vice versa. Specifically: A dyne is a CGS force unit, and kilogram-force under standard gravity.
Formula
kilogram-forces = dynes × 0.00000101971621298
This factor comes from each unit's defined relationship to the category's base unit: 1 dyne equals 0.00001 base units, and 1 kilogram-force equals 9.80665 base units, so dividing one by the other gives the direct dyne-to-kilogram-force factor of 0.00000101971621298.
Simple example
1 dyn × 0.000001019716213 = 0.0000010197 kgf
1 dyne = 0.0000010197 kilogram-forces.
Real-world example
10 dyn × 0.000001019716213 = 0.0000101972 kgf
10 dynes = 0.0000101972 kilogram-forces.
Conversion table
| Dyne (dyn) | Kilogram-force (kgf) |
|---|---|
| 1 dyn | 0.0000010197 kgf |
| 5 dyn | 0.0000050986 kgf |
| 10 dyn | 0.0000101972 kgf |
| 50 dyn | 0.0000509858 kgf |
| 100 dyn | 0.0001019716 kgf |
| 1,000 dyn | 0.0010197162 kgf |
Reverse conversion: Kilogram-force to Dyne
0.0000010197 kgf × 980665 = 0.9999841005 dyn
0.0000010197 kilogram-forces = 0.9999841005 dynes.
dynes = kilogram-forces × 980665

Understanding the Dyne (dyn)
A dyne is a CGS force unit.
Understanding the Kilogram-force
Kilogram-force (kgf) measures force. Defined as the force exerted by standard gravity on a mass of one kilogram — exactly 9.80665 newtons. It is classified as a non-SI unit, deprecated but still encountered.
Where it's used: Still encountered in some older European and Asian engineering specifications and torque-related equipment, though official use has been phased out in favor of the newton
Kilogram-force vs. newton. The newton is the modern SI unit of force; kilogram-force is an older, gravity-dependent unit still occasionally seen on legacy equipment. 1 kgf equals exactly 9.80665 N.
Uses of the Kilogram-force today
- Appears on some older or legacy engineering and mechanical specifications, particularly torque wrenches and spring-force ratings, predating wider adoption of the newton

Frequently asked questions
How many kilogram-forces are in 1 dyne?
1 dyne equals 0.0000010197 kilogram-forces, using the exact defined conversion factor rather than an estimate.
How do I convert dyne to kilogram-force?
Multiply the dyne value by 0.000001019716213. The converter above does this instantly to whatever precision you set.
How do I convert kilogram-force back to dyne?
Use the reverse factor: 1 kilogram-force equals 980,665 dynes. You can also use the swap control in the converter above to flip the direction instantly.
What is a dyne?
Dyne (dyn) is a unit of force.
What is a kilogram-force?
Kilogram-force (kgf) measures force. Defined as the force exerted by standard gravity on a mass of one kilogram — exactly 9.80665 newtons. It is classified as a non-SI unit, deprecated but still encountered.
Is the dyne to kilogram-force conversion exact?
Yes. Defined as the force exerted by standard gravity on a mass of one kilogram — exactly 9.80665 newtons. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
What is the difference between kilogram-force vs. newton?
The newton is the modern SI unit of force; kilogram-force is an older, gravity-dependent unit still occasionally seen on legacy equipment. 1 kgf equals exactly 9.80665 N.
