As an American...
Science uses the metric system, allowing the entire world to share scientific data simply, with no need to deal with clumsy conversions.
Most other nations in the entire world use the metric system.
The metric system is as easy as counting to ten. Literally. It's a system of 10. I mean...
how hard is that?!
We've had decades to standardize with the rest of the world, not just because of standardization (which makes
everything easier), but because metric makes
logical sense.
Which the latter is probably why we have not switched to it. It makes too much damned sense for the average American to grasp. It must be just "too hard" to learn. Waa. Either that, or we just want to be special snowflakes when, news flash, we're still just people living on this planet with other people, and it makes no damned sense whatsoever to make communication across borders harder than it needs to be.
Let alone in the space future, with space nations, across lightyears of space... space.
Edit:
Earlier I stated aviation uses metric internationally. On further consideration, that isn't entirely accurate, and I removed it from the above post. In fact, aviation is an
absolute clusterfrak. It's also a
good example of
why standardization works.
We use metric for temperature calculations, imperial feet for altitude, and knots for speed. All of which is all over the board.
HOWEVER, because it is standardized internationally as what is used in aviation, no matter where you go in the world the calculations, speeds, and altitudes are understood. Standardization keeps things sane and, as a result, safe.
