Note that in German this is “Quadrillion” nicely verbalizing exponentiation via ‘quad’=‘four’ times multiplication of million.
I didn’t know that. German is my own native language (and AFAIK many others work the same). I’m not very good with large numbers (I usually count them: “million, milliard, billion, billiard...”), so that helps.
It is easy. For example Avogadros number is roughly 10^-24 (for the purpose of estimating numbers of particles in natural phenomena) thus 24=4∙6 thus million^4 thus “Quadrillion” in German. And one googol is 10^100 and 100 = 16∙6+3+1 thus 10 “Sedezilliarden” (from 16=sedecem) albeit all this doesn’t work in English at least not so easily.
Now I’m venturing into off-topic territory, but:
