That's how the conversion is done. I think that Ray's point was that we don't know the precision of "a foot of snow" in this case. If it was given as 12 inches, it might mean anything from 11.5 inches to just under 12.5 inches. "A foot" could easily be the description if there was somewhat less precision than that. My guess is that John used the precise conversion lest he confuse someone if, for example, he had written 30 cm. Or perhaps even confuse someone even more by checking again and finding that official metric reading was e.g. 32.4 cm. -- Tom Marchant
