Ounce-inch (ozf·in)
The ounce-inch (ozf·in) is the torque of one ounce-force at one inch, about 7.06 mN·m.
Symbol: ozf·in (ASCII: ozf-in)
Quantity: torque (moment of force)
SI relation: 1 ozf·in = 0.007061551814226 N·m (exact)
Derivation: 1 ozf·in = 1/16 lbf·in = 0.00706155181 N·m
Exact: yes, by definition
Typical uses
- Stepper and servo motor holding torque
- Small DC motors and gearboxes
