Metric system is IMPOSSIBLE for carpentry!

Carpentry has its own set of measures, at least for lumber dimensions. It would seem logical that if you stack two 2x4s you'd have a 4x4. No.

Of course, my carpentry experience is from working on old (for these purposes, 40 years and up) houses, where nothing is square, nothing is plumb, nothing is level, and all figures to the right-hand side of the decimal are not to be trusted.

Those are the dimensions of the wood when it is cut but before it it is planed and sanded down. That's why two 2X4's don't equal one 4X4.
