Newton-meters to Foot-pounds Converter

Convert torque from newton meters (N·m) to foot-pounds (lbf·ft), with inch-pounds and other torque units alongside.

What this tool does

Convert torque from newton meters (N·m) to foot-pounds (lbf·ft), with inch-pounds and other torque units alongside. Type an amount in newton meters, choose the units, and the tool converts it to pound-force feet. It offers 5 torque units and also shows the same amount in the others.

Inputs

  • Value: A number.
  • From: Choose one: Newton meter, Pound-force foot, Pound-force inch, Kilogram-force meter, Ounce-force inch. Starts as Newton meter.
  • To: Choose one of the same 5 units as "From". Starts as Pound-force foot.

How to use

  1. Enter the amount you want to convert.
  2. Choose the unit to convert from and the unit to convert to.
  3. 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.

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
