About Converting Attonewton meters to Femtonewton meters
Attonewton 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: Attonewton meter is 1e-18 newton meter units, and femtonewton meter is 1e-15 newton meter units.
Formula
femtonewton meters = attonewton meters × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 attonewton meter equals 1e-18 base units, and 1 femtonewton meter equals 1e-15 base units, so dividing one by the other gives the direct attonewton meter-to-femtonewton meter factor of 0.001.
Simple example
1 aN m × 0.001 = 0.001 fN m
1 attonewton meter = 0.001 femtonewton meters.
Real-world example
10 aN m × 0.001 = 0.01 fN m
10 attonewton meters = 0.01 femtonewton meters.
Conversion table
| Attonewton meter (aN m) | Femtonewton meter (fN m) |
|---|---|
| 1 aN m | 0.001 fN m |
| 5 aN m | 0.005 fN m |
| 10 aN m | 0.01 fN m |
| 50 aN m | 0.05 fN m |
| 100 aN m | 0.1 fN m |
| 500 aN m | 0.5 fN m |
Reverse conversion: Femtonewton meter to Attonewton meter
0.001 fN m × 1000 = 1 aN m
0.001 femtonewton meters = 1 attonewton meter.
attonewton meters = femtonewton meters × 1000
