Convert Pound-feet to Newton centimeters
1 pound-foot is 135.58 N·cm. One pound-foot is exactly 135.581794833 newton centimeters.
One pound-foot is 135.58179 newton centimeters. To convert pound-feet to newton centimeters, multiply by 135.58179; to go the other way, divide by 135.58179 or multiply by 0.0073756215. 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. The torque of one pound-force at one 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.
The same converter answers this pair however it is written: pound-feet to newton centimetres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert pound-feet to newton centimeters? The converter and the working
- 1.Take the measurement in pound-feet.
- 2.Multiply by 135.58179 — that is how many newton centimeters fit in one pound-foot.
- 3.To go back the other way, divide by 135.58179, or multiply by 0.0073756215.
Worked example: 25 pound-feet to newton centimeters
- Formula
- lbf·ft × 135.58179 = N·cm
- Arithmetic
- 25 × 135.58179 = 3,389.54 N·cm
- Answer
- 25 lbf·ft = 3,389.54 N·cm
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a newton centimeter?
A hundredth of a newton meter, used where a newton meter is too coarse: electronics assembly, optics, small screws.
How many newton centimeters are in a pound-foot?
One pound-foot is 135.58179 newton centimeters. Going the other way, one newton centimeter is 0.0073756215 pound-feet. 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.
