Convert Pound-inches to Pound-feet
1 pound-inch is 0.08 lbf·ft. One pound-inch is exactly 0.0833333333333 pound-feet.
One pound-inch is 0.083333333 pound-feet. To convert pound-inches to pound-feet, multiply by 0.083333333; to go the other way, divide by 0.083333333 or multiply by 12. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Special Publication 811. One twelfth of a pound-foot.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert pound-inches to pound-feet? The converter and the working
- 1.Take the measurement in pound-inches.
- 2.Multiply by 0.083333333 — that is how many pound-feet fit in one pound-inch.
- 3.To go back the other way, divide by 0.083333333, or multiply by 12.
Worked example: 25 pound-inches to pound-feet
- Formula
- lbf·in × 0.083333333 = lbf·ft
- Arithmetic
- 25 × 0.083333333 = 2.08 lbf·ft
- Answer
- 25 lbf·in = 2.08 lbf·ft
The factor is rounded for display; the figure above is computed from the full value.

What is a pound-inch?
One twelfth of a pound-foot. Small fasteners, spark plugs and bicycle components are specified here, which is why a spec of "80 in-lb" is not a misprinted 80 ft-lb.
What is a pound-foot?
The torque of one pound-force at one foot. Exact, because a pound-force is exactly 4.4482216152605 newtons and a foot is exactly 0.3048 meters. Every US torque wrench is marked in these.
How many pound-feet are in a pound-inch?
One pound-inch is 0.083333333 pound-feet. Going the other way, one pound-foot is 12 pound-inches. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
Every torque unit here
The whole group — 5 units with their symbols and the size of each one in newton meters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a pound-inch.
