Last I heard, the estimate for mammals was around 1 Mb=1cM.

Most organisms turn out to have a similar number of total 
recombination events, so I think that ~2000 cM is standard, and
you can get an approximation of the size of a cM by dividing the
genome size by that. I don't know whether this holds for the
organisms with very high "C" values like plants and amphibians,
but they generally are hard to work with genetically anyway.
