About Converting Newton meters to Hectonewton meters
Newton meter and Hectonewton 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. Newton meter is most often used for torque wrench specifications (bolt tightening) outside the us.
Formula
hectonewton meters = newton meters × 0.01
This factor comes from each unit's defined relationship to the category's base unit: 1 newton meter equals 1 base unit, and 1 hectonewton meter equals 100 base units, so dividing one by the other gives the direct newton meter-to-hectonewton meter factor of 0.01.
Simple example
1 N m × 0.01 = 0.01 hN m
1 newton meter = 0.01 hectonewton meters.
Real-world example
10 N m × 0.01 = 0.1 hN m
10 newton meters = 0.1 hectonewton meters.
Conversion table
| Newton meter (N m) | Hectonewton meter (hN m) |
|---|---|
| 1 N m | 0.01 hN m |
| 5 N m | 0.05 hN m |
| 10 N m | 0.1 hN m |
| 50 N m | 0.5 hN m |
| 100 N m | 1 hN m |
| 500 N m | 5 hN m |
Reverse conversion: Hectonewton meter to Newton meter
0.01 hN m × 100 = 1 N m
0.01 hectonewton meters = 1 newton meter.
newton meters = hectonewton meters × 100

Understanding the Newton meter
Newton meter (N m) measures torque. The newton-meter is the SI derived unit of torque: one newton of force applied at one meter of leverage. It is classified as a SI derived unit.
Where it's used: Standard scientific and automotive torque unit worldwide except the US
Uses of the Newton meter today
- Torque wrench specifications (bolt tightening) outside the US
- Engine torque specifications internationally
- Mechanical and structural engineering
History of the Newton meter
As a coherent SI derived unit, the newton-meter follows automatically from the newton and meter, without an independent historical origin — though it is numerically identical in form to the joule (energy), the two are conventionally kept distinct because torque and energy are physically different quantities.
Historical origin. Newton meter was not the invention of a single named person; it developed through the process described above.
Understanding the Hectonewton meter (hN m)
Hectonewton meter is 100 newton meter units.

Frequently asked questions
How many hectonewton meters are in 1 newton meter?
1 newton meter equals 0.01 hectonewton meters, using the exact defined conversion factor rather than an estimate.
How do I convert newton meter to hectonewton meter?
Multiply the newton meter value by 0.01. The converter above does this instantly to whatever precision you set.
How do I convert hectonewton meter back to newton meter?
Use the reverse factor: 1 hectonewton meter equals 100 newton meters. You can also use the swap control in the converter above to flip the direction instantly.
What is a newton meter?
Newton meter (N m) measures torque. The newton-meter is the SI derived unit of torque: one newton of force applied at one meter of leverage. It is classified as a SI derived unit.
What is a hectonewton meter?
Hectonewton meter (hN m) is a unit of torque.
Is the newton meter to hectonewton meter conversion exact?
Yes. Both newton meter and hectonewton meter are defined by fixed standards rather than physical artifacts, so the factor of 0.01 used above is exact to as many digits as you choose to display.
Where is the newton meter still used today?
Standard scientific and automotive torque unit worldwide except the US
