About This Calculator
This free online inch-pounds to foot-pounds converter instantly converts between these two common torque measurement units. Enter any value in inch-pounds (in-lb) and get the corresponding value in foot-pounds (ft-lb) using the standard conversion formula: 1 foot-pound = 12 inch-pounds.
Both inch-pounds and foot-pounds are units of torque — the rotational force applied to an object around an axis. One foot-pound equals the torque resulting from one pound of force applied at the end of a one-foot lever. Similarly, one inch-pound is the torque from one pound of force at the end of a one-inch lever. Since there are 12 inches in a foot, converting between these units is a simple division or multiplication by 12.
This conversion is essential in automotive repair, where torque specifications for bolts and nuts are given in foot-pounds (e.g., lug nuts) or inch-pounds (e.g., small engine components). Mechanics, engineers, and DIY enthusiasts regularly need to convert between these units when using different torque wrenches or following manufacturer specifications from various regions.
The United States primarily uses imperial torque units (in-lb and ft-lb), while most other countries use newton-meters (Nm). If you need to convert to Nm, check our Inch Lbs To Nm Converter. For applications like aerospace and precision instrumentation, accurate torque conversion is critical for safety and performance.
Frequently Asked Questions
How do I convert inch-pounds to foot-pounds?
To convert inch-pounds to foot-pounds, divide the number of inch-pounds by 12. For example, 24 inch-pounds divided by 12 equals 2 foot-pounds. This calculator does the math instantly for you.
What is the difference between inch-pounds and foot-pounds?
Inch-pounds (in-lb) and foot-pounds (ft-lb) are both units of torque. One foot-pound equals 12 inch-pounds. Inch-pounds are used for smaller torque measurements like precision tools, while foot-pounds are used for larger applications like automotive lug nuts and construction bolts.
When should I use inch-pounds vs foot-pounds?
Use inch-pounds for smaller torque specifications such as electronics, small engine components, and precision equipment. Use foot-pounds for larger applications like automotive wheel lugs, engine bolts, suspension components, and construction fasteners. Most torque wrenches are calibrated in one unit or the other.
Is this inch-pounds to foot-pounds converter free?
Yes, this inch-pounds to foot-pounds converter is completely free to use with no registration, downloads, or hidden fees. Convert as many values as you need.
How accurate is this conversion tool?
This converter uses the exact conversion factor of 1/12 (0.0833333) for inch-pounds to foot-pounds, providing mathematically precise results. The calculation is exact since 1 foot = 12 inches, so the conversion is a simple division with no rounding error.
Can I convert foot-pounds back to inch-pounds?
Yes, to convert foot-pounds back to inch-pounds, multiply the foot-pound value by 12. For example, 10 foot-pounds multiplied by 12 equals 120 inch-pounds. Our calculator focuses on the inch-pounds to foot-pounds direction, but the reverse calculation is straightforward.
What industries use inch-pounds and foot-pounds torque measurements?
Automotive repair, aerospace engineering, construction, manufacturing, and mechanical engineering all use torque measurements extensively. Mechanics use torque wrenches to tighten bolts to manufacturer specifications measured in foot-pounds or inch-pounds, ensuring safety and proper component function.
