Formula
Foot-Pounds = Inch-Pounds / 12
Since there are exactly 12 inches in one foot, dividing inch-pounds by 12 gives foot-pounds. To convert foot-pounds to inch-pounds, multiply by 12. For newton-meters, multiply inch-pounds by 0.112985 or foot-pounds by 1.35582.
Frequently Asked Questions
How many inch-pounds are in one foot-pound?
There are exactly 12 inch-pounds in one foot-pound. This relationship comes directly from the fact that there are 12 inches in one foot. Since torque is calculated as force multiplied by the distance from the pivot point, a force of one pound applied at a distance of one foot produces the same torque as that pound applied at twelve inches. This makes the conversion straightforward: divide inch-pounds by 12 to get foot-pounds, or multiply foot-pounds by 12 to get inch-pounds.
When should I use inch-pounds versus foot-pounds?
Inch-pounds are typically used for smaller, more precise torque applications such as tightening screws on electronics, small engine carburetor adjustments, firearm scope mounts, and delicate mechanical assemblies. Foot-pounds are used for larger fasteners and heavier applications like automotive lug nuts, engine cylinder head bolts, and structural bolting. As a general guideline, if the torque specification is less than about 20 foot-pounds (240 inch-pounds), using inch-pounds provides better granularity and precision.
Can I use a foot-pound torque wrench for inch-pound specifications?
While mathematically you can convert the values, most foot-pound torque wrenches lack the precision needed for accurate inch-pound work. A typical foot-pound wrench has a minimum setting around 10 ft-lbs (120 in-lbs) and increments of 1 ft-lb (12 in-lbs). For specifications requiring exact inch-pound values like 30 in-lbs (2.5 ft-lbs), you need a dedicated inch-pound torque wrench that can measure in smaller increments, typically 1 in-lb. Using the wrong scale wrench can result in over-tightening delicate fasteners.
Are inch-pounds and inch-ounces related?
Yes, inch-ounces are an even smaller unit of torque. There are 16 inch-ounces in one inch-pound, following the standard ounce-to-pound conversion. Inch-ounces are used for extremely delicate applications like adjusting watch mechanisms, calibrating precision instruments, or setting drag on fishing reels. To convert inch-ounces to inch-pounds, divide by 16. To convert inch-ounces to foot-pounds, divide by 192 (16 times 12).
How do I get the most accurate result?
Enter values as precisely as possible using the correct units for each field. Check that you have selected the right unit (e.g. kilograms vs pounds, meters vs feet) before calculating. Rounding inputs early can reduce output precision.
