It seems to me that having both -s(ectors) and -S(ize) would be a good 
solution, as long as the man page is clear on the distinction.  Or maybe 
something like '-ss' for "size in sectors" vs. '-sb' for "size in bytes" 
would be even easier to remember.

Are you thinking of giving an explicit error message in case both are 
given?  It might be nice to spell it out - something like "specify size in 
sectors or bytes, not both" perhaps.


(And for what it's worth, I would expect that passing '-s 1M' should still 
mean a sector count and not silently change the interpretation.)
