About Converting Femtonewton meters to Kilonewton meters
Femtonewton meter and Kilonewton 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. Specifically: Femtonewton meter is 1e-15 newton meter units, and kilonewton meter is 1000 newton meter units.
Formula
kilonewton meters = femtonewton meters × 1e-18
This factor comes from each unit's defined relationship to the category's base unit: 1 femtonewton meter equals 1e-15 base units, and 1 kilonewton meter equals 1000 base units, so dividing one by the other gives the direct femtonewton meter-to-kilonewton meter factor of 1e-18.
Simple example
1 fN m × 1e-18 = 1e-18 kN m
1 femtonewton meter = 1e-18 kilonewton meters.
Real-world example
10 fN m × 1e-18 = 1e-17 kN m
10 femtonewton meters = 1e-17 kilonewton meters.
Conversion table
| Femtonewton meter (fN m) | Kilonewton meter (kN m) |
|---|---|
| 1 fN m | 1e-18 kN m |
| 5 fN m | 5e-18 kN m |
| 10 fN m | 1e-17 kN m |
| 50 fN m | 5e-17 kN m |
| 100 fN m | 1e-16 kN m |
| 500 fN m | 5e-16 kN m |
Reverse conversion: Kilonewton meter to Femtonewton meter
1e-18 kN m × 1e+18 = 1 fN m
1e-18 kilonewton meters = 1 femtonewton meter.
femtonewton meters = kilonewton meters × 1e+18
