About Converting Nanonewtons to Kilogram-forces
Nanonewton and Kilogram-force both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Nanonewton is 1e-9 newton units, and kilogram-force under standard gravity.
Formula
kilogram-forces = nanonewtons × 1.019716e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 nanonewton equals 1e-9 base units, and 1 kilogram-force equals 9.80665 base units, so dividing one by the other gives the direct nanonewton-to-kilogram-force factor of 1.019716e-10.
Simple example
1 nN × 1.019716e-10 = 1.019716e-10 kgf
1 nanonewton = 1.019716e-10 kilogram-forces.
Real-world example
100 nN × 1.019716e-10 = 1.019716e-8 kgf
100 nanonewtons = 1.019716e-8 kilogram-forces.
Conversion table

| 50 nN | 5.098581e-9 kgf |
| 100 nN | 1.019716e-8 kgf |
| 500 nN | 5.098581e-8 kgf |
| 1,000 nN | 1.019716e-7 kgf |
Reverse conversion: Kilogram-force to Nanonewton
1.019716e-10 kgf × 9806650000 = 0.9999997911 nN
1.019716e-10 kilogram-forces = 0.9999997911 nanonewtons.
nanonewtons = kilogram-forces × 9806650000

Understanding the Nanonewton (nN)
Nanonewton is 1e-9 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 nanonewton?
1 nanonewton equals 1.019716e-10 kilogram-forces, using the exact defined conversion factor rather than an estimate.
How do I convert nanonewton to kilogram-force?
Multiply the nanonewton value by 1.019716e-10. The converter above does this instantly to whatever precision you set.
How do I convert kilogram-force back to nanonewton?
Use the reverse factor: 1 kilogram-force equals 9,806,650,000 nanonewtons. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanonewton?
Nanonewton (nN) is a unit of engineering.
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 nanonewton 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.
