What this tool does
Convert moment of force (torque) between newton meters, foot-pounds, inch-pounds, kilogram-force meters and other torque units. Type an amount in newton meters, choose the units, and the tool converts it to pound-force feet. It offers 14 torque units and also shows the same amount in the others.
Inputs
- Value: A number.
- From: Choose one from 14 options, including Newton meter, Kilonewton meter, Millinewton meter, Newton centimeter, Newton millimeter, Kilogram-force meter. Starts as Newton meter.
- To: Choose one of the same 14 units as "From". Starts as Pound-force foot.
How to use
- Enter the amount you want to convert.
- Choose the unit to convert from and the unit to convert to.
- Read the result: the converted amount and the same amount in the other units. It appears once every required field has a valid value.
Worked examples
Conversions from newton meters to pound-force feet:
- 1 N·m ≈ 0.737562 lbf·ft
- 5 N·m ≈ 3.687811 lbf·ft
- 10 N·m ≈ 7.375621 lbf·ft
- 50 N·m ≈ 36.878107 lbf·ft
- 100 N·m ≈ 73.756215 lbf·ft
Multiply the number of newton meters by about 0.737562 to get pound-force feet. The factor follows from exact definitions. It has more digits than fit here, so it is shown rounded.
Sources: Newton meter: SI Brochure, 9th edition (2019). Pound-force foot: exact by definition.
Limitations
- Converts a torque value from one unit to another. It does not work out the torque a bolt, engine or motor needs.
- Always check the torque in the manufacturer's specification, and note which unit it is written in.
FAQs
- Q: Is moment of force the same as torque?
- A: For this conversion, yes. Moment of force and torque are measured in the same units, such as newton meters and pound-force feet.
- Q: Why do kilogram-force and pound-force appear in the list?
- A: They are force units used in older and engineering torque specifications. One kilogram-force is exactly 9.80665 newtons (standard gravity), and one pound-force is about 4.448 newtons.
