About Converting Millinewton meters to Exanewton meters
Millinewton meter and Exanewton 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: Millinewton meter is 0.001 newton meter units, and exanewton meter is 1000000000000000000 newton meter units.
Formula
exanewton meters = millinewton meters × 1e-21
This factor comes from each unit's defined relationship to the category's base unit: 1 millinewton meter equals 0.001 base units, and 1 exanewton meter equals 1e+18 base units, so dividing one by the other gives the direct millinewton meter-to-exanewton meter factor of 1e-21.
Simple example
1 mN m × 1e-21 = 1e-21 EN m
1 millinewton meter = 1e-21 exanewton meters.
Real-world example
10 mN m × 1e-21 = 1e-20 EN m
10 millinewton meters = 1e-20 exanewton meters.
Conversion table
| Millinewton meter (mN m) | Exanewton meter (EN m) |
|---|---|
| 1 mN m | 1e-21 EN m |
| 5 mN m | 5e-21 EN m |
| 10 mN m | 1e-20 EN m |
| 50 mN m | 5e-20 EN m |
| 100 mN m | 1e-19 EN m |
| 500 mN m | 5e-19 EN m |
Reverse conversion: Exanewton meter to Millinewton meter
1e-21 EN m × 1e+21 = 1 mN m
1e-21 exanewton meters = 1 millinewton meters.
millinewton meters = exanewton meters × 1e+21
