Americans used .45's the Germans 9mm's...who one the war.

I think you mean "who WON the war." And that had absolutely nothing to do with it.

A pound of feathers and a pound of gold.

A pound of feathers ( avoirdupois ) = 16 ounces = 0.453 592 37 kg

1 ounce ( avoirdupois ) = 28.349 523 g

A pound of gold ( troy or apothecary ) = 12 troy ounces = 0.373 241 721 6 kg

1 ounce gold (troy or apothecary ) = 31.103 476 8 g

As an Engineer who has worked extensively in both metric and imperial I make the following comments:

Every person I know who has converted fully to metric would never willingly go back to imperial.
The people who complain about metric are the ones who have never bothered to learn and use metric.
There are fewer errors when people use metric compared with imperial. While there are many who use imperial accurately and correctly it is more difficult and time consuming to learn everything you need in imperial and it is more time consuming to check and ensure accuracy.
The questions about dimensioning things is only a problem when you do hard conversions from imperial. In metric manufacturing typically moves to sensible dimensions over time. For example a steel column that is 6" square over time will become 150mm x 150mm not the hard conversion of 152 x 152.
Metric is not perfect but on the balance it is superior to imperial, you just have to get used to it.
Overall metric is better.

Just a young fellow I'm guessing.

BTW I am a Journeyman fabricator fully capable with both Imperial and metric.

Of course, I'm not an Engineer.

No, I am an old fella who has been in the business for 30 plus years. Use imperial because I have to not because I want to. Went to school using imperial switched to metric at university and back to imperial when I came to Canada. Am totally familiar with both system and have used both very extensively. Metric is better. Fewer screw up, error etc. Not perfect but better.

I want to know why they cant make the finished dimention of a 2x4 actually measure 2x4?

Starts out as a 2" x 4", after planing etc. it is the way they are sold.

I realize you know that and I agree.

Why is a .38 Special bullet 0.357" diameter?

Why is a .44 Magnum called such when the actual bullet diameter is 0.429"?

Darned if I know, LOL!

Because they can't make as many studs that way. Over the years the original 2x4 which was cut at surprise surprise 2"x4" and then dresses has been down sized. They are now 1 1/2"x 3 1/2" dressed. You get a lot more of the smaller size out of a tree but can sell them for the same price. Kind of like yoghurt containers have got smaller.

starts out as a 2" x 4", after planing etc. It is the way they are sold. Not quite true. This was originally they case but the undressed size is now 1 3/4" x 3 3/4".

I realize you know that and i agree.

Why is a .38 special bullet 0.357" diameter? Just the way it used to be measured. From the rifling to rifling vs the modern way of land to land. You will find the same for most old cartridge types.

Why is a .44 magnum called such when the actual bullet diameter is 0.429"? See above.

Darned if i know, lol!

see comments above next to the questions.

9mm vs .45 was answered back in the 80's

Economically, I think that the Germans and Japanese may have WON the war...
