It could be worse Bruce, you could have grown up in Canada during the conversion to metric and learned half and half.
I generally think in miles/feet/inches regarding distance, and mph for speed, but thinking of them in metric as well is second nature. Temperatures in Farenheit confuse me, I have to mentally convert to a close temp in Celcius, except for certain ranges of temperatures that are common. Weight is pounds, and I have to convert kilos to pounds for them to make sense. About the only thing I have down: I was an electronics technician in the Navy so 12/24hr time is thoughtless for me.

I do have to say though, in general, metric measurements make more sense, and are pretty much universally factors of 10, which makes them easier to work with.

Cheers,
Graham
