Torque unit notes
Foot-pound-force and inch-pound-force measure torque. They describe force acting across a lever arm.
These symbols are sometimes written as lb-ft and lb-in. This calculator treats those forms as torque aliases.
Foot-pounds can also describe energy in other contexts. Always confirm the intended physical quantity.
Frequently asked questions
How many inch-pounds equal one foot-pound?
One foot-pound equals exactly twelve inch-pounds.
How do I convert ft-lb to in-lb?
Multiply the foot-pound value by twelve.
How do I convert in-lb to ft-lb?
Divide the inch-pound value by twelve.
Are lb-ft and ft-lb the same torque unit?
