Frequently Asked Questions
How do I convert Foot Pounds to Inch Pounds?
Multiply the ft·lbf value by 12.0000. For example, 1 ft·lbf = 12.0000 in·lbf, and 5 ft·lbf = 60.00 in·lbf.
What is the formula for Foot Pounds to Inch Pounds?
The formula is in·lbf = ft·lbf × 12.0000. To convert back: ft·lbf = in·lbf × 0.083333.
What is Foot-pound force (ft·lbf)?
It is the standard US/Imperial torque unit, equal to 1.3558 N·m. It is widely used in the American automotive industry for bolt torque specifications.
What is Inch-pound force (in·lbf)?
It is a US/Imperial unit for smaller torque values, equal to 0.1130 N·m. It is common for small fasteners and precision assembly.
Is this converter accurate?
Yes. The factor 12 is exact (12 inches per foot), and the tool uses internationally recognized conversion factors with high precision — suitable for engineering and mechanical work.
Can I convert other torque units?
Yes. Enable additional units to see Newton-meters (N·m), foot-pounds (ft·lbf), inch-pounds (in·lbf), kilogram-force meters (kgf·m), and many more — all from a single input value.
