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.
Kilogram-force centimeter
A kilogram-force centimeter is exactly 0.0980665 newton meters, the usual unit on servo motor specs (kg·cm).

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 kilogram-force centimeters are in one ounce-inch?

1 ozf·in = 0.0720078 kgf·cm exactly.

How do I convert ounce-inches to kilogram-force centimeters?

Use kgf·cm = ozf·in × 0.07200778874. For example, 25 ozf·in = 1.80019 kgf·cm.

How many ounce-inches are in one kilogram-force centimeter?

1 kgf·cm = 13.8874 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.
