About Converting Exanewtons to Kilogram-forces
Exanewton 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: Exanewton is 1000000000000000000 newton units, and kilogram-force under standard gravity.
Formula
kilogram-forces = exanewtons × 1.019716e+17
This factor comes from each unit's defined relationship to the category's base unit: 1 exanewton equals 1e+18 base units, and 1 kilogram-force equals 9.80665 base units, so dividing one by the other gives the direct exanewton-to-kilogram-force factor of 1.019716e+17.
Simple example
1 EN × 1.019716e+17 = 1.019716e+17 kgf
1 exanewton = 1.019716e+17 kilogram-forces.
Real-world example
10 EN × 1.019716e+17 = 1.019716e+18 kgf
10 exanewtons = 1.019716e+18 kilogram-forces.

Understanding the Exanewton (EN)
Exanewton is 1000000000000000000 newton units.
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 exanewton?
1 exanewton equals 1.019716e+17 kilogram-forces, using the exact defined conversion factor rather than an estimate.
How do I convert exanewton to kilogram-force?
Multiply the exanewton value by 1.019716e+17. The converter above does this instantly to whatever precision you set.
How do I convert kilogram-force back to exanewton?
Use the reverse factor: 1 kilogram-force equals 9.80665e-18 exanewtons. You can also use the swap control in the converter above to flip the direction instantly.
What is a exanewton?
Exanewton (EN) 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 exanewton 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.
