I grew up in America, and was used to the Imperial/US system (they're not quite the same). Now I'm becoming more used to the metric system, which I've always liked, but a lot of things I can't visualise, such as a 15cm or whatever cock. It's sll what you are used to for familiarity, but for calculation, metric is much easier. I really like it for cooking, especially weighing things that I used to measure in cups.
