Inch-Pounds to Foot-Pounds Converter

Torque is the measure of the rotational force applied to an object, typically calculated as force multiplied by distance. Because a foot is equal to 12 inches, the mathematical relationship between foot-pounds (ft-lb) and inch-pounds (in-lb) is straightforward. To convert foot-pounds to inch-pounds, you multiply the value in foot-pounds by 12. Conversely, to convert inch-pounds to foot-pounds, you divide the value in inch-pounds by 12. The core equation is: inPounds = ftPounds * 12.

Imagine you are working on a bicycle repair project, and the manufacturer manual specifies a stem bolt torque setting of 108 inch-pounds. However, your torque wrench only displays readings in foot-pounds. To find the correct setting, you divide 108 inch-pounds by 12. The math looks like this: 108 / 12 = 9 foot-pounds. You simply set your wrench to 9 ft-lb to achieve the precise clamping force required.

Always double-check your tool settings before applying torque to critical automotive or aerospace components. Using inch-pounds on a fastener that requires high foot-pounds can lead to catastrophic under-tightening, while using foot-pounds where inch-pounds are specified will easily snap bolts and strip threads. When in doubt, convert your units twice to ensure absolute precision.
