I dont know why they have to lie about it. At $5/8ft board you’d think I paid for the full 1.5. Edit: I mixed up nominal with actual.

It’s not exactly a lie, just a standard. Nominal board sizes were based on the unfinished lumber size. Another 1/4 inch is taken off each side to get a smooth surface that makes it easier to work with.
Here’s an old image (reddit warning)

that shows the rough cuts of boards from a log. When they look at a log, they determine how many of each size they can get from it, and at that point, a 2x4 is 2 inches by 4 inches.
Why does the consumer need to know the dimensions at harvest when it’s been processed multiple times?
That’s like calling an 4oz can of evaporated milk a gallon because it came from a gallon of milk before processing (I have no clue on the ratio)
I agree with this. Use whatever system you need or want internally, but there’s no reason to force whatever archaic or industry system onto a consumer. Logcutters also use a 1"=1/4 system and that is how they sell wood. A piece of wood that is 2" thick is sold as 8/4. Not 2". I get that they have their system but it seems dickish to force the consumer to use that system. There could be a good argument for it, but I’ve not heard one beyond “what, can’t you do math?”
It’s like a 1/4lb paddy being a different weight before and after cooking. They can’t tell you the final weight, since it’s always going to be different. Same with wood.
The woods final actual dimensions can vary, so they tell you its original size.
A 2x10 can be anywhere from 9-3/8thick down do 8-3/4 depending on how it dries.
I get that. But this is for kiln dried wood. And this particular issue I’m removeding about isn’t about net loss. It’s selling wood using an internally useful measuring system instead of how the consumer would actually think about it. It’s adding needless complexity, in my mind, when there’s enough factors to consider.
The consumer (people who work with lumber) knows how the system works. You don’t, because you don’t work with lumber.
If the boards were precisely measured in mm and binned accordingly, it would help no one because all construction techniques developed for use with lumber account for dimensional inaccuracy.
Building and working with lumber is different than working with manufactured materials like plywood or whatever.
