How many newton-meters are in one inch-pound?

1 inch-pound (in·lb) equals exactly 0.1129848290276167 newton-meters (N·m). This is derived from the international inch (0.0254 m) and the pound-force (4.44822 N).

How do I convert inch-pounds to newton-meters?

Multiply the in·lb value by 0.112985. For example, 50 in·lb × 0.112985 = 5.649 N·m. This tool performs the calculation automatically in real time.

What is the relationship between in·lb and ft·lb?

There are exactly 12 inch-pounds in one foot-pound (ft·lb). So 1 ft·lb = 12 in·lb, and 1 in·lb = 0.08333 ft·lb. Inch-pounds are used for smaller torque values where foot-pounds would give unwieldy fractions.

How do I convert newton-meters to inch-pounds?

Multiply the N·m value by 8.85075. For example, 10 N·m × 8.85075 = 88.5 in·lb. Use the N·m input field above for instant reverse conversion.

When should I use inch-pounds instead of foot-pounds?

Inch-pounds are typically used for smaller torque values — under about 10 ft·lb (120 in·lb). Common applications include sensor fittings, electronic connectors, small engine components, bicycle hardware, and precision instruments.

Are in·lb and lb·in the same unit?

Yes. "Inch-pound" (in·lb) and "pound-inch" (lb·in) refer to the same torque quantity — one pound-force at one inch radius. The numerical value is identical regardless of which word order is used.
