ozf·in
ounce-force inch
Torqueexact by definition
The ounce-force inch is exactly 0.00706155181422604 newton metres. It is the universal rating unit for small DC and stepper motors in North America, along with fractional-torque screwdrivers and instrument springs.
Watch out: There are 16 ozf·in to the lbf·in and 192 to the lbf·ft. A NEMA 17 stepper rated 45 oz·in is 0.32 N·m; reading the number as inch-pounds would overstate it sixteenfold.
