"even" just means divisible by two. So it's not unique at all. Two is the only prime that's ~~even~~ divisible by two and three is the only prime that's divisible by three. You just think two is a special prime because there is a word for "divisible by two" but the prime two isn't any more special or unique in any meaningful way than any other prime.

Wow that was fast I just edited my previous comment and you probably mean "1 and prime numbers" by numberphile with james grime.

Any examples? Sounds like you mean the reason why one is excluded from the primes because of the fundamental theorem of arithmetic.

And how is "even" special? Two is the only prime that's divisible by two but three is also the only prime divisible by three.

IIRC the US already uses metric (technically). The imperial units are defined in terms of metric units.
