I'm interested in collecting 'rules of thumb'.  That is, the conversion
factors that rely on expert knowledge (or mindless repetition), rather
than universally accepted values.  How many litres/gallons of paint to
paint 100 full depth supers?  How many board feet/metres of timber to
create 100 boxes? How many lb/kg wax from extracting 1 ton/tonne of
honey?  How many pounds/kilos of nails for 100 supers?  Be sure to
include all your assumptions: full depth/half depth boxes?  How many
nails in each corner? etc.
