SUMMARY
The discussion clarifies the distinction between the torque units inch-lb and inch-lbf. Participants confirm that inch-lb is not a valid torque unit, as it incorrectly uses a unit of mass instead of force. The correct term is inch-lbf, where 1 lbf represents the force exerted by a 1 lb mass under standard gravity. For practical applications, users are advised to replace lb with lbf when calculating torque, ensuring accurate measurements.
