Pound-force Inch (lbf·in)
Definition: A finer US customary torque unit equal to the twisting effect of a 1-pound-force applied at a 1-inch radius, used for smaller fasteners than pound-force foot comfortably describes.
History: Derived from pound-force foot via the standard 12-inches-per-foot relationship, adopted for small-fastener torque specifications where foot-scale units would be imprecise.
Current use: The standard unit for small bolt and screw torque specifications in US automotive, electronics, and appliance assembly, commonly seen on inch-pound torque screwdrivers and small torque wrenches.
Gram-force Meter (gf·m)
Definition: A very small gravitational torque unit equal to the twisting effect produced by the weight of a 1-gram mass applied at a 1-meter radius.
History: A lighter-scale extension of the same pre-SI gravitational metric convention as kilogram-force meter, useful for describing extremely small torque values.
Current use: Occasionally used for tiny precision instrument torque specifications, such as delicate clockwork or micro-motor mechanisms, though gram-force centimeter is more commonly seen in practice for such applications.

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 Pound-force Inch → Gram-force Meter: multiply by 11.521246. For example, 1 lbf·in × 11.521246 = 11.521246 gf·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 lbf·in equals 11.521246 gf·m. For scale, a mid-size sedan's engine might produce around 300 N·m of peak torque — roughly 2655.2237 lbf·in — 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 Gram-force Meters are in 1 Pound-force Inch?
1 Pound-force Inch (lbf·in) equals exactly 11.521246 Gram-force Meters (gf·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.
