Well, I guess it's common to mix up units--I recall a speech by a businessman, I forgot who, who was often asked, "how much money do you make?"--an informal way of saying "how many dollars per year"--but he always, just to illustrate that the proper unit is money per time, not just money, would reply, "$11,000". He'd wait a few seconds, then add, "per minute."
