What is difference between in-lb and inch-lbf?

[ram18]

Hi friends,

I have so much confusion between torque unit Inch -lb and inch -lbf .

I think inch-lb = inch-lbf

i know that 1 lbf = 32.2 lb.ft / sec^2

I need 2500000 inch-lbf torque required so i consider lb-inch .

Thanks,

lb is a unit of mass, so inch-lb isn't a torque. They probably mean inch-lbf, where 1 lbf is the weight of a 1 lb mass.

So yea, just replace lb with lbf without changing the numbers.

Just so you know, outside of school, no one ever refers to the output of a torque wrench as anything other than (spoken) 'inch pound', 'inch ounce' or 'foot pound'. Yes, it's actually a pound-force or ounce-force, but it's just not used.

Same sort of thing when people call bolts, screws.
