I have never had a problem with using Metric measurements. It is so much easier than calculating in 3 Different types of coinage. Weight and length. Once you get it it is much easier. I measure in centimetres.
My father kept pointing out that in the war, he was making rivets etc, to hold together probably airplanes and God knows what else, and that the "international units" were millimetres. That's what comes of having a mechanical engineer for a father though.
