About Converting Rontonewton meters to Nanonewton meters
Rontonewton meter and Nanonewton 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: Rontonewton meter is 1e-27 newton meter units, and nanonewton meter is 1e-9 newton meter units.
Formula
nanonewton meters = rontonewton meters × 1e-18
This factor comes from each unit's defined relationship to the category's base unit: 1 rontonewton meter equals 1e-27 base units, and 1 nanonewton meter equals 1e-9 base units, so dividing one by the other gives the direct rontonewton meter-to-nanonewton meter factor of 1e-18.
Simple example
1 rN m × 1e-18 = 1e-18 nN m
1 rontonewton meter = 1e-18 nanonewton meters.
Real-world example
10 rN m × 1e-18 = 1e-17 nN m
10 rontonewton meters = 1e-17 nanonewton meters.
Conversion table
| Rontonewton meter (rN m) | Nanonewton meter (nN m) |
|---|---|

| 5 rN m | 5e-18 nN m |
| 10 rN m | 1e-17 nN m |
| 50 rN m | 5e-17 nN m |
| 100 rN m | 1e-16 nN m |
| 500 rN m | 5e-16 nN m |
Reverse conversion: Nanonewton meter to Rontonewton meter
1e-18 nN m × 1e+18 = 1 rN m
1e-18 nanonewton meters = 1 rontonewton meters.
rontonewton meters = nanonewton meters × 1e+18
