A rod is an old English form of measurement that, I believe, is really only used in measuring allotments these days. It seems to be highly inaccurate if you ask me as all plots seem to be slightly different sizes on my site (probably they started out accurate and got wonky over time) but one rod is effectively a little over five metres and it's also known sometimes as a 'perch'.
I have a feeling that modern councils are getting rid of the rod and it seems a bit of a shame. However arcane, there's something rather romantic about a council sending me a bill for rental of a piece of land measured in Ancient Roman units...
