How it works
We use ft-lb = in-lb x 0.0833333333333.
Exact relationship: 1 in-lb = 0.0833333333333 ft-lb.
Example: 10 in-lb = 0.833 ft-lb.
Notes: Results are rounded in the default view.
Examples
- 10 in-lb = 0.833 ft-lb
- 100 in-lb = 8.333 ft-lb
- 500 in-lb = 41.667 ft-lb
FAQ
What physical quantity do inch-pounds and foot-pounds express?
Inch-pounds express smaller torque values where foot-pounds would be too coarse for practical fastening and adjustment work. Foot-pounds express torque in customary engineering contexts and are widely used in mechanical assembly and vehicle service work.
What is the difference between inch-pounds and foot-pounds?
Inch-pounds and foot-pounds both express torque, but they come from different engineering conventions and are used in different tool, vehicle, and machine ecosystems.
What is the history of the inch-pound?
Inch-pounds come from the same customary torque tradition as foot-pounds and remain useful for smaller fasteners and precision assembly.
What is the history of the foot-pound?
Foot-pounds grew from customary force-and-distance engineering practice and remain common in U.S. torque specifications.
Were the inch-pound and foot-pound discovered by a specific person?
Inch-pounds are a conventional engineering unit, not a discovery attributed to one person. Foot-pounds emerged from engineering convention and standardization rather than discovery by one person.
Where are inch-pounds and foot-pounds used in science and engineering?
Inch-pounds are used for electronics, small fasteners, covers, clamps, instrumentation, and precision assembly settings. Foot-pounds are common in automotive service manuals, fastener charts, wrench settings, and U.S.-oriented machine maintenance.
Why do torque units matter in calculations?
Torque units affect wrench settings, fastener integrity, shaft loading, machine setup, and maintenance outcomes. Using the wrong torque unit can cause direct hardware damage or safety risk.
Can I trust this for critical calculations?
Use this for convenience and verify against your governing standard, service manual, or controlled engineering document for critical work. Torque values often tie directly to safety and reliability.
