About Converting Hectonewton meters to Pound-feet
Hectonewton meter and Pound-foot 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: Hectonewton meter is 100 newton meter units, and torque from one pound-force at one foot.
Formula
pound-feet = hectonewton meters × 73.7562149277
This factor comes from each unit's defined relationship to the category's base unit: 1 hectonewton meter equals 100 base units, and 1 pound-foot equals 1.35581794833 base units, so dividing one by the other gives the direct hectonewton meter-to-pound-foot factor of 73.7562149277.
Simple example
1 hN m × 73.75621493 = 73.75621493 lb ft
1 hectonewton meter = 73.75621493 pound-feet.
Real-world example
10 hN m × 73.75621493 = 737.5621493 lb ft
10 hectonewton meters = 737.5621493 pound-feet.

Understanding the Hectonewton meter (hN m)
Hectonewton meter is 100 newton meter units.
Understanding the Pound-foot
Pound-foot (lb ft) measures torque. A pound-foot is the torque from one pound-force applied at one foot of leverage: exactly 1.3558179483314004 newton-meters. It is classified as a US/imperial customary unit.
Where it's used: United States (automotive and mechanical torque specifications)
Pound-foot vs. foot-pound. Pound-foot (torque) and foot-pound (energy/work) use the same two units but measure physically different quantities; US convention typically orders them differently to help distinguish which is meant, though usage isn't always consistent.
Uses of the Pound-foot today
- US torque wrench specifications (bolt tightening)
- US automotive engine torque specifications
- US mechanical and construction trades
History of the Pound-foot
The pound-foot follows from pound-force and the foot, both standardized through English and later international agreements, remaining the standard US automotive and mechanical torque unit even as most other measurements shifted toward metric in engineering contexts.
Historical origin. Pound-foot was not the invention of a single named person; it developed through the process described above.
Pound-foot — sources
- NIST Special Publication 811 — Documents the pound-foot's exact newton-meter equivalence.

Frequently asked questions
How many pound-feet are in 1 hectonewton meter?
1 hectonewton meter equals 73.75621493 pound-feet, using the exact defined conversion factor rather than an estimate.
How do I convert hectonewton meter to pound-foot?
Multiply the hectonewton meter value by 73.75621493. The converter above does this instantly to whatever precision you set.
How do I convert pound-foot back to hectonewton meter?
Use the reverse factor: 1 pound-foot equals 0.0135581795 hectonewton meters. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectonewton meter?
Hectonewton meter (hN m) is a unit of torque.
What is a pound-foot?
Pound-foot (lb ft) measures torque. A pound-foot is the torque from one pound-force applied at one foot of leverage: exactly 1.3558179483314004 newton-meters. It is classified as a US/imperial customary unit.
Is the hectonewton meter to pound-foot conversion exact?
Yes. A pound-foot is the torque from one pound-force applied at one foot of leverage: exactly 1.3558179483314004 newton-meters. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
What is the difference between pound-foot vs. foot-pound?
Pound-foot (torque) and foot-pound (energy/work) use the same two units but measure physically different quantities; US convention typically orders them differently to help distinguish which is meant, though usage isn't always consistent.
