They are taught it, but many apparently dont memorise it, because they dont care.
We memorize it. It's all base 10 increments; it's not hard.
The Imperial standard, on the other hand, would be harder to memorize when introduced to it as a secondary form of measurement, but that doesn't matter to anyone who isn't permanently moving to the U.S. or U.K. Alas and alack, it really doesn't matter what Americans use to measure things in their own everyday lives, and is therefore a poor choice on your part to advocate against on this thread. The worst thing I've experienced is when working on a car, and the bolt size is metric when I thought it was Imperial, and vice versa. Ratchet and wrench sets are sold with both measurements nowadays, anyway, so that's only a minor annoyance that does not need the attention of the U.S. government right now, or ever.
As a side, Fahrenheit is superior to Celsius outside of the laboratory, and I will defend my poor and innocent temperature scale to my death.
