🔧 Inch-Pounds to Foot-Pounds Converter
Convert torque values between inch-pounds and foot-pounds, plus see the equivalent in Newton-meters.
Inch-pounds vs. foot-pounds
Both inch-pounds (in-lb) and foot-pounds (ft-lb) measure torque — the twisting force applied by a wrench or fastener — but they use different length units for the lever arm. Since one foot equals 12 inches, one foot-pound equals 12 inch-pounds.
How this calculator works
Enter your torque value and choose the direction of conversion. To go from inch-pounds to foot-pounds, the calculator divides by 12; to go the other way, it multiplies by 12. The result is also shown in Newton-meters, the SI unit of torque, using the conversion factor 1 ft-lb = 1.3558 N·m.
- 1 foot-pound = 12 inch-pounds
- 1 foot-pound ≈ 1.356 Newton-meters
Getting torque units right matters for safely tightening fasteners — many small hardware specs use inch-pounds, while larger bolts and automotive specs often use foot-pounds. Always check your torque wrench and the manufacturer’s specification before tightening critical fasteners.
