Civil Construction - Conversions Factors to know

[LAMEngineer]

Hello all,

Without having access to the handy Conversions Factors booklet with every imaginable conversion there is, I was wondering if there is a handful of factors I should try to dedicate to memory. Such as; acres to miles^2 (640). etc. (stuff that is not listed in the PE civil reference handbook from NCEES version 1.1, section 1.2).

Thanks!
