  3. Swap the direction to convert back, or copy the result.

How it is calculated

ozf·in = N·m × 141.6119327

Multiply the value in newton meters by 141.6119327 to get ounce-inches.

Example

To convert 25 N·m to ounce-inches: 25 × 141.6119327 = 3,540.3 ozf·in.

About the units

Newton meter
The SI unit of torque: the torque of a one newton force acting at a one meter lever arm.
Ounce-inch
The ounce-inch (ozf·in) is one ounce-force at a one inch arm, one sixteenth of a pound-inch, common for servo and stepper motors.

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
  • Both unit factors are exact by their official definitions.

Questions about this tool

How many ounce-inches are in one newton meter?

1 N·m = 141.612 ozf·in exactly.

How do I convert newton meters to ounce-inches?

Use ozf·in = N·m × 141.6119327. For example, 25 N·m = 3,540.3 ozf·in.

How many newton meters are in one ounce-inch?

1 ozf·in = 0.00706155 N·m.

Is a pound-foot the same as a foot-pound?

For torque, yes: both mean one pound-force on a one foot arm, about 1.3558 newton meters. Engineers often write pound-foot (lbf·ft) for torque and foot-pound for energy to keep the two apart.

Why is torque not measured in joules if both are newton meters?

Torque is a force times a lever arm at right angles to it, while work is a force times a distance along it. The dimensions match, but by convention torque is always given in newton meters.
