Newton Meter (N·m)
Definition: The SI derived unit of torque, equal to the rotational "twisting" effect produced by a 1-newton force applied at a 1-meter radius from the axis of rotation.
History: Formed from the SI newton and meter, becoming the standard torque unit once the newton was adopted internationally in 1948 — the same underlying unit as bending moment, but conventionally labeled "torque" when describing rotation about an axis, such as engine crankshafts, motor shafts, and fasteners, rather than beam bending.
Current use: The standard unit for engine torque ratings, electric motor specifications, and torque wrench markings in every country using the metric system, and increasingly common on US automotive spec sheets alongside pound-force feet.
Kilonewton Meter (kN·m)
Definition: Equal to 1,000 newton meters, used for very large torque values such as those produced by heavy industrial machinery and large engines.
History: Adopted as the practical large-scale SI multiple of the newton meter, mirroring the kilonewton's role for force, once industrial and marine engine torque outputs began reaching into the thousands of newton meters.
Current use: Used for large diesel and marine engine torque ratings, wind turbine drivetrain specifications, and heavy industrial gearbox and crankshaft torque capacities.

How Torque Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the newton meter. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Newton Meter → Kilonewton Meter: multiply by 0.001. For example, 1 N·m × 0.001 = 0.001 kN·m.
Engine Torque and Horsepower
Engine torque is the twisting force a crankshaft delivers at a given moment, and it's what actually gets a vehicle moving from a stop — horsepower, by contrast, is torque multiplied by engine speed (rpm), so a high-torque engine can feel much stronger off the line even with a modest horsepower rating. Torque wrenches use these same units to tighten fasteners to a manufacturer-specified value: too little torque and a bolt can loosen under vibration, too much and it can strip threads, stretch the fastener past its yield point, or crack the material it's threaded into.
Torque vs. Moment of Force: Same Physics, Different Context
Torque and moment of force share the exact same units and formula (force × radius or lever-arm distance), but engineering convention reserves "torque" for twisting effects on rotating shafts, engines, motors, and fasteners, while "moment" describes bending effects in stationary structures like beams and columns. There's no physical difference between a "50 N·m torque" and a "50 N·m moment"; the distinction is purely about which kind of problem — a spinning drivetrain versus a static beam — an engineer is solving, which is why this site offers a separate Moment of Force Converter for the structural use case.
Example
1 N·m equals 0.001 kN·m. For scale, a mid-size sedan's engine might produce around 300 N·m of peak torque — roughly 300 N·m — while a typical lug nut on a passenger car is torqued to about 100-140 N·m with a torque wrench during a tire change.
Frequently Asked Questions
How many Kilonewton Meters are in 1 Newton Meter?
1 Newton Meter (N·m) equals exactly 0.001 Kilonewton Meters (kN·m).
What's the difference between torque and horsepower?
Torque is the twisting force an engine or motor produces at a given instant; horsepower is torque multiplied by rotational speed (rpm), representing the rate at which work is done. An engine can have high torque at low rpm (good for towing and acceleration off the line) without necessarily having high peak horsepower, which depends on how well torque is sustained across the rev range.
Why do torque wrench specifications sometimes use kgf·cm or lbf·in instead of N·m?
Torque specifications scale with fastener size: large bolts (engine mounts, lug nuts) are naturally reported in newton meters or pound-force feet, while small fasteners (electronics, small appliances, camera mounts) need finer-grained units like newton centimeters, kilogram-force centimeters, or pound-force/ounce-force inches to avoid awkward decimals.
How accurate are these conversions?
Every conversion factor used here is the exact, internationally recognized value (e.g. 1 lbf·ft = exactly 1.3558179483314 N·m, derived from the internationally standardized pound, foot, and standard gravity) — results are limited only by floating-point display precision, not by rounded conversion constants.
