How many inch-pounds are in one foot-pound?

1 foot-pound (ft·lb) equals exactly 12 inch-pounds (in·lb). This is exact because one foot is defined as exactly twelve inches.

How do I convert foot-pounds to inch-pounds?

Multiply the ft·lb value by 12. For example, 25 ft·lb × 12 = 300 in·lb. To go the other way, divide in·lb by 12.

What is a foot-pound of torque?

A foot-pound (ft·lb) is the torque produced by a one-pound force acting at a perpendicular distance of one foot from a pivot point. It is the standard torque unit in US automotive and construction applications.

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

Inch-pounds are used for smaller torque values, such as those found in small fasteners, electronics, bicycles, and precision instruments. Foot-pounds are common for larger applications like engines and structural bolts.

Is ft·lb the same as lb·ft?

Yes. "Foot-pound" (ft·lb) and "pound-foot" (lb·ft) refer to the same torque unit. The terms are used interchangeably in engineering and automotive contexts.

What torque tools are calibrated in inch-pounds?

Many bicycle torque wrenches, small precision torque screwdrivers, and electronic component assembly tools are calibrated in in·lb. Larger automotive torque wrenches typically use ft·lb.
