About Converting Millinewton meters to Petanewton meters
Millinewton meter and Petanewton 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 petanewton meter is 1000000000000000 newton meter units.
Formula
petanewton meters = millinewton meters × 1e-18
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 petanewton meter equals 1e+15 base units, so dividing one by the other gives the direct millinewton meter-to-petanewton meter factor of 1e-18.
Simple example
1 mN m × 1e-18 = 1e-18 PN m
1 millinewton meter = 1e-18 petanewton meters.
Real-world example
10 mN m × 1e-18 = 1e-17 PN m
10 millinewton meters = 1e-17 petanewton meters.
Conversion table
| Millinewton meter (mN m) | Petanewton meter (PN m) |
|---|---|
| 1 mN m | 1e-18 PN m |
| 5 mN m | 5e-18 PN m |
| 10 mN m | 1e-17 PN m |
| 50 mN m | 5e-17 PN m |
| 100 mN m | 1e-16 PN m |
| 500 mN m | 5e-16 PN m |
Reverse conversion: Petanewton meter to Millinewton meter
1e-18 PN m × 1e+18 = 1 mN m
1e-18 petanewton meters = 1 millinewton meter.
millinewton meters = petanewton meters × 1e+18
