How it is calculated
N·m = ozf·in × 0.007061551814
Multiply the value in ounce-inches by 0.007061551814 to get newton meters.
Example
To convert 25 ozf·in to newton meters: 25 × 0.007061551814 = 0.176539 N·m.

About the units
- 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.
- Newton meter
- The SI unit of torque: the torque of a one newton force acting at a one meter lever arm.
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 newton meters are in one ounce-inch?
1 ozf·in = 0.00706155 N·m exactly.
How do I convert ounce-inches to newton meters?
Use N·m = ozf·in × 0.007061551814. For example, 25 ozf·in = 0.176539 N·m.
How many ounce-inches are in one newton meter?
1 N·m = 141.612 ozf·in.
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.
