I have to say life would be easier in the long run though it would be a massive pain. I am Canadian and was raised on the metric system in school, but being raised in a family with carpenters, and tradesmen I have a better natural understanding of imperial measurements. I can judge distances accurately and weights in feet, inches and pounds but when it comes to metric I may as well be blind, I have to either measure it or use a calculator. In Canada if you want to built something the permit boards and city require your plans in metric, but then when you want to build it you have to convert to feet and inches when you go to get your supplies at the lumber yard anyways. I just find it weird and kind of useless. But must admit traveling in km feels like Im going farther on one tank of gas heheh
