same here, all over the place with imperial and metric. Volumes for me are in metric, Ferm temp in C, mash temp in F, and weights in pounds / ounces.
Whatever works I guess. Not really thinking of changing any time soon unless there was a real need for it.
I remember the first time I saw a grain bill in metric...my first thought was that buddy didn't have enough grain for a 5GAL batch..hehe!
