Maybe: Number::Spell provides functionality for spelling out numbers. Currently only integers are supported.

Update: Avogadro's constant should be the party-opener...

Do you know that there are more than six vigintillion elementary entities per mol?

(in response to 921420 below) ... but then, I found that vigintillion is 1063, not 1023! The modules source also sais it's 1021*3. So maybe this one will work? Do you know that a vigintillion has the prime factorisation 263 x 563? Different bases but same exponents - incredible! (see: also)
