How to Use This Calculator
Enter the torque in inch-pounds
Type the torque rating taken from fastener specs, torque wrenches, or equipment manuals.
See foot-pounds instantly
The converter divides by 12 to show lb·ft, the standard for larger fasteners and vehicle specs.
Use the extra units as needed
Refer to N·m and oz·in when coordinating with metric documentation or delicate assemblies.
Formula
lb·ft = lb·in ÷ 12
Because there are 12 inches in a foot, torque in foot-pounds is simply inch-pounds divided by 12. Newton-meter conversion uses 1 lb·ft = 1.3558179483 N·m.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Inch-pounds and foot-pounds are both part of the imperial torque family, but each is tailored to different hardware sizes. This calculator ensures you maintain accuracy when switching between small fastener torque (lb·in) and automotive or industrial torque (lb·ft).
Additional outputs in N·m and oz·in support documentation that requires SI values or very fine torque adjustments, such as electronic assembly and instrumentation.

Frequently Asked Questions
Is the 12:1 ratio always exact?
Yes. One foot equals exactly 12 inches, so torque conversions between lb·in and lb·ft simply involve dividing or multiplying by 12.
Do I need to convert inch-ounces separately?
No. The calculator provides inch-ounce results automatically (multiply inch-pounds by 16).
Can I use this for torque wrench calibration?
Yes. The calculator relies on precise unit relationships, making it suitable for calibration reference values.
Does it support negative torque values?
Negative inputs are allowed, representing torque applied in the reverse direction. All outputs preserve the sign.
