Foot-Pound to Inch-Pound Calculator

A Foot-Pound to Inch-Pound Calculator converts torque values between imperial units for automotive torque, fastener tightening, mechanical assembly, torque wrench settings, and engineering calculations with accurate conversion factors.

What Are Foot-Pounds?

Foot-pounds (ft-lb) measure torque or rotational force produced when one pound of force acts at a distance of one foot from a pivot point. Engineers, mechanics, and technicians use this unit in automotive torque specifications, industrial equipment maintenance, torque wrench calibration, and mechanical fastening applications. Foot-pounds represent a standard torque measurement within US customary units and many engineering systems.

What Are Inch-Pounds?

Inch-pounds (in-lb) measure torque using one pound of force applied at a distance of one inch from the rotation point. This unit is common for small fasteners, electrical components, bicycle assemblies, aerospace equipment, and precision mechanical systems. Inch-pound values provide greater control when tightening delicate hardware where accurate torque specifications and calibrated torque tools are essential.

Foot-Pound to Inch-Pound Formula

Convert foot-pounds to inch-pounds by multiplying the torque value by 12. This standard conversion factor applies across mechanical engineering and torque measurement applications.

Practical Example Foot-Pound to Inch-Pound Conversions

Formula

$Inch\ Pounds = Foot\ Pounds \times 12$

Example 1

$5\ ft!-!lb \times 12 = 60\ in!-!lb$

Example 2

$15\ ft!-!lb \times 12 = 180\ in!-!lb$

Example 3

$25\ ft!-!lb \times 12 = 300\ in!-!lb$

This formula ensures accurate torque conversion for fasteners, torque wrenches, calibration procedures, and mechanical assembly tasks.
