Inch-Pounds to Foot-Pounds Converter

Divide by 12: 1 foot-pound equals 12 inch-pounds exactly, because a foot is 12 inches. So 120 inch-pounds ÷ 12 = 10 foot-pounds, 36 inch-pounds ÷ 12 = 3 foot-pounds, and 150 inch-pounds ÷ 12 = 12.5 foot-pounds. To convert foot-pounds to inch-pounds, multiply by 12 instead.

120 inch-pounds equals 10 foot-pounds exactly (120 ÷ 12 = 10). In metric units that is 13.5582 newton-metres. 120 inch-pounds is a common torque-wrench benchmark because it is the top of many inch-pound wrench ranges and the bottom of most foot-pound wrench ranges.

36 inch-pounds equals 3 foot-pounds exactly (36 ÷ 12 = 3), which is 4.0675 newton-metres. Similarly, 60 inch-pounds is 5 foot-pounds (6.7791 newton-metres) and 240 inch-pounds is 20 foot-pounds (27.1164 newton-metres).

Multiply by 12. For example, 7.5 foot-pounds × 12 = 90 inch-pounds (10.1686 newton-metres), 2.5 foot-pounds × 12 = 30 inch-pounds (3.3895 newton-metres), and 0.75 foot-pounds × 12 = 9 inch-pounds (1.0169 newton-metres).

One inch-pound equals 0.1130 newton-metres and one foot-pound equals 1.3558 newton-metres, by the exact definitions 1 lbf = 4.4482216152605 N and 1 in = 0.0254 m. So 1200 inch-pounds (100 foot-pounds) equals 135.5818 newton-metres.

The unit matches the size of the fastener. Inch-pound wrenches (typically 20–200 inch-pounds, i.e. 1.6667–16.6667 foot-pounds) give fine resolution for small bolts such as spark plugs and valve covers. Foot-pound wrenches (typically 10–150 foot-pounds, i.e. 120–1800 inch-pounds) suit larger jobs like lug nuts. Using an inch-pound wrench on a small fastener avoids the coarse rounding of a foot-pound scale.

Yes, exactly. Inch-pounds and foot-pounds measure the same physical quantity (torque) on different scales, and 1 foot-pound = 12 inch-pounds by definition. The inch-pound is the finer unit: 1 inch-pound equals 0.0833 foot-pounds, and 1 foot-pound equals 12 inch-pounds.

150 inch-pounds equals 12.5 foot-pounds (150 ÷ 12 = 12.5), which is 16.9477 newton-metres. A torque spec of 150 inch-pounds sits right at the boundary between typical inch-pound and foot-pound wrench ranges.

240 inch-pounds equals 20 foot-pounds exactly (240 ÷ 12 = 20), which is 27.1164 newton-metres. Other common values: 180 inch-pounds = 15 foot-pounds (20.3373 newton-metres) and 600 inch-pounds = 50 foot-pounds (67.7909 newton-metres).

There are exactly 12 inch-pounds in 1 foot-pound. Common foot-pound values in inch-pounds: 5 foot-pounds = 60 inch-pounds, 10 foot-pounds = 120 inch-pounds, 80 foot-pounds = 960 inch-pounds, and 150 foot-pounds = 1800 inch-pounds.

Spark plugs are typically tightened to 100–156 inch-pounds (8.3333–13 foot-pounds, about 11.2985–17.6256 newton-metres) depending on the engine, so an inch-pound torque wrench is the right tool. Always follow the manufacturer's specification in the unit it was published in, and convert only when your wrench reads the other unit.

Yes. This converter runs entirely in your browser with no server requests: the conversion is the exact ratio 1 foot-pound = 12 inch-pounds, and the newton-metre values use the exact definitions of the pound-force and the inch.
