I use Imperial all the time! All my rulers and tapes are Imperial, although I do have a 10 ' tape that has both so that I can convert measurements to Imperial. I tried to convert but made too many mistakes using metric (I hate Napoleon). I always think Imperial re. weights and measures and my wife who is only 46, thinks first in Imperial and then metric, perhaps shopping and cooking has something to do with it, with most groceries sold in metric. I can picture a 6' person but not someone 1.84 centimetres ? tall! Dollars and cents are ok, they're easier than the old Pounds, shillings and pence.
