The Inch-Pounds to Newton-Meters Converter converts torque values from inch-pounds (in·lb) to newton-meters (N·m) using the conversion factor 1 in·lb = 0.112985 N·m. Inch-pounds are commonly used for specifying torque on smaller fasteners, precision assemblies, and electronic components where foot-pounds would give inconveniently small numbers.
In American engineering practice, inch-pounds are the preferred unit for torque values below about 10 ft·lb (120 in·lb). Applications include small machine screws, electrical connections, carburetor jets, small engine components, circuit board standoffs, and instrument assemblies. Many torque screwdrivers and small torque wrenches are calibrated in inch-pounds.
Converting inch-pounds to newton-meters is essential when working with international specifications, as the metric world consistently uses N·m regardless of the magnitude. A fastener specified at 60 in·lb in a US manual will be specified at 6.8 N·m in the international version of the same manual.
Our converter also provides the equivalent in foot-pounds (ft·lb) using the exact relationship 1 ft·lb = 12 in·lb, useful when switching between torque wrench scales.
The formula is: N·m = in·lb × 0.112985. This derives from: 1 in·lb = 1 ft·lb / 12 = 1.35582 / 12 = 0.112985 N·m. For foot-pounds: ft·lb = in·lb / 12 (exact). The inch-pound is exactly 1/12 of a foot-pound since 1 foot = 12 inches.
Common small-fastener torque values: electronics screws 5-10 in·lb (0.56-1.13 N·m), carburetor jets 15-25 in·lb (1.7-2.8 N·m), small machine screws 20-40 in·lb (2.3-4.5 N·m), valve cover bolts 70-100 in·lb (7.9-11.3 N·m), thermostat housing 100-120 in·lb (11.3-13.6 N·m).

1 in·lb = 0.112985 N·m. So about 8.85 in·lb = 1 N·m.
Use inch-pounds for torque values below about 120 in·lb (10 ft·lb) — small fasteners, screws, and precision assemblies. Use foot-pounds for larger fasteners and structural bolts.
Divide by 12. For example, 120 in·lb = 10 ft·lb exactly, since 1 foot = 12 inches.
Beam-type torque wrenches, torque screwdrivers, and small click-type wrenches. Digital torque adapters can also display in·lb.
25 in·lb = 2.824625 N·m ≈ 2.8 N·m.
Yes, for very small torques (watch mechanisms, micro-electronics). 1 in·oz = 1/16 in·lb = 0.007062 N·m.
A torque screwdriver rated from 1-20 in·lb (0.1-2.3 N·m) is suitable for most electronics work. Look for ±6% accuracy or better.
For a SAE Grade 5 bolt: 75 in·lb (8.5 N·m) dry, about 55 in·lb (6.2 N·m) lubricated. Always check the specific bolt grade and material.
Inch-pounds provide finer granularity than foot-pounds for small fasteners. At 10 in·lb, a ±10% tolerance is only ±1 in·lb, useful for precision assemblies.
Only if it reads low enough. Many standard torque wrenches start at 10 or 20 ft·lb. For in·lb work, use a dedicated low-range torque wrench or torque screwdriver.
