About Converting Kilogram-force meters to Piconewton meters
Kilogram-force meter and Piconewton meter both measure torque, and the conversion is essential for anyone using a torque wrench specified in one unit against a bolt or engine spec given in the other. Kilogram-force meter is most often used for appears on some legacy torque specifications and equipment predating wider adoption of the newton-meter.
Formula
piconewton meters = kilogram-force meters × 9.80665e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 kilogram-force meter equals 9.80665 base units, and 1 piconewton meter equals 1e-12 base units, so dividing one by the other gives the direct kilogram-force meter-to-piconewton meter factor of 9.80665e+12.
Simple example
1 kgf m × 9.80665e+12 = 9.80665e+12 pN m
1 kilogram-force meter = 9.80665e+12 piconewton meters.
Real-world example
10 kgf m × 9.80665e+12 = 9.80665e+13 pN m
10 kilogram-force meters = 9.80665e+13 piconewton meters.
Conversion table
| Kilogram-force meter (kgf m) | Piconewton meter (pN m) |
|---|---|
| 1 kgf m | 9.80665e+12 pN m |
| 5 kgf m | 4.903325e+13 pN m |
| 10 kgf m | 9.80665e+13 pN m |
| 50 kgf m | 4.903325e+14 pN m |
| 100 kgf m | 9.80665e+14 pN m |
| 500 kgf m | 4.903325e+15 pN m |
Reverse conversion: Piconewton meter to Kilogram-force meter
9.80665e+12 pN m × 1.019716e-13 = 1 kgf m
9.80665e+12 piconewton meters = 1 kilogram-force meter.
kilogram-force meters = piconewton meters × 1.019716e-13

Understanding the Kilogram-force meter
Kilogram-force meter (kgf m) measures torque. The torque produced by one kilogram-force acting at a perpendicular distance of one meter. It is classified as a non-SI unit, deprecated but still encountered.
Where it's used: Can be encountered in some older European and Japanese automotive and mechanical torque specifications
kgf·m vs. N·m. The newton-meter is the modern SI torque unit; kilogram-force meter is the older, gravity-dependent equivalent still occasionally seen on legacy specifications. 1 kgf·m equals exactly 9.80665 N·m.
