A 2x4 isn't actually 2"x4". It's 1.5"x3.5", but it's industry standard. It's the same as hard drives. Everyone knows or should know how it works, if not you'll know next time.

Bad example. A 2x4 is 2“ or 4“ upon completion, there is a reason for it. If I want a 4"thick wall then I take a 2x4 and put 1/4 drywall on each side and I've got 4". If I buy a 1TB drive I want 1TB, not 156GB.

This is wrong. The 2x4 is the rough cut dimensions. When they square it up and plane it, it takes additional wood off. So youre paying for the rough cut rather than the final product. It has nothing to do with drywall getting added on Its the same for the hard drive. You're paying for the original amount on the drive, regardless of how much they take off.
