What Is an Inch-Pound?

The inch-pound (in·lb) is a small unit of torque equal to the force of one pound applied at one inch from the pivot point. It is used for small, precise fasteners where foot-pounds would be too coarse — electronics, bicycle components, firearms, and instrument screws.

What Is a Foot-Pound?

The foot-pound (ft·lb) is the standard US torque unit, equal to one pound-force at one foot from the pivot. Since 1 foot = 12 inches, the relationship between these units is exact: 12 in·lb = 1 ft·lb.

Inch-Pounds to Foot-Pounds Formula

To convert in·lb to ft·lb, divide by 12:

ft·lb = in·lb ÷ 12

This is an exact conversion — no rounding error. 12 inches = 1 foot, so 12 in·lb = 1 ft·lb exactly.

Worked Example

Convert 89 in·lb to ft·lb: 89 ÷ 12 = 7.42 ft·lb. 89 in·lb is a common automotive torque spec (various small fasteners).

Inch-pounds for small, precise fasteners (electronics, bicycle components, firearms, screws under ~10 ft·lb). Foot-pounds for larger fasteners (wheels, engine bolts, suspension).

What is 89 inch pounds in foot pounds?

89 ÷ 12 = 7.42 ft·lb. This is a common torque spec for various automotive fasteners. If your torque wrench reads in ft·lb, set it to about 7.4.

Can I use a foot-pound torque wrench for inch-pound specs?

Only if it has fine enough graduation. Most ft·lb wrenches start at 10 ft·lb (120 in·lb). For specs under 10 ft·lb, you need a dedicated inch-pound torque wrench for accuracy.
