Damn, I did 2 years of physics studies but I never heard about atto and exa. Though I did spend a lot of time to try to memorise the other ones.
Just wait until you hear about zetta (10^21) and yotta (10^24) and their inverses zepto (10^-21) and yocto (10^-24). :D
Huh, neat! When fact-checking my statement, I just learned that there are even two more prefixes on each side of the scale: ronna (10^27), quenna (10^30), ronto (10^-27) and quecto (10^-30). They got added last year.
I’m waiting for the day when planck length (1.6 * 10^-35 m) has its own prefix.
