oz·in²
ounce square inch
Moment of inertiaexact by definition
The ounce square inch is exactly 1.8289978... × 10⁻⁵ kg·m², one sixteenth of a pound square inch. Small stepper and servo motors in North America publish rotor inertia in oz·in² alongside their oz·in torque.
Watch out: Oz·in² is an inertia and oz·in is a torque, and both appear on the same datasheet one line apart. The squared inch is the only thing separating them in print.
