If rotor were 1000 pounds you would have 0.504 inch-pounds allowable residual unbalance. To convert to inch-ounce, multiply by 16 inch-ounce / inch-pound and the result is a max allowable residual unbalance of 8 inch-ounce. A shortcut to all the above: allowable inch-ounce = 6 * G * W / N. where: G is ISO grade.
