About Converting Teranewton meters to Femtonewton meters
Teranewton meter and Femtonewton 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: Teranewton meter is 1000000000000 newton meter units, and femtonewton meter is 1e-15 newton meter units.
Formula
femtonewton meters = teranewton meters × 1e+27
This factor comes from each unit's defined relationship to the category's base unit: 1 teranewton meter equals 1e+12 base units, and 1 femtonewton meter equals 1e-15 base units, so dividing one by the other gives the direct teranewton meter-to-femtonewton meter factor of 1e+27.
Simple example
1 TN m × 1e+27 = 1e+27 fN m
1 teranewton meter = 1e+27 femtonewton meters.
Real-world example
10 TN m × 1e+27 = 1e+28 fN m
10 teranewton meters = 1e+28 femtonewton meters.
Conversion table
| Teranewton meter (TN m) | Femtonewton meter (fN m) |
|---|---|
| 1 TN m | 1e+27 fN m |
| 5 TN m | 5e+27 fN m |
| 10 TN m | 1e+28 fN m |
| 50 TN m | 5e+28 fN m |
| 100 TN m | 1e+29 fN m |
| 500 TN m | 5e+29 fN m |
Reverse conversion: Femtonewton meter to Teranewton meter
1e+27 fN m × 1e-27 = 1 TN m
1e+27 femtonewton meters = 1 teranewton meters.
teranewton meters = femtonewton meters × 1e-27
