Though I'm American, I use metric units almost exclusively in work and really even outside work. I don't really use imperial units for short measurements other than to occasionally translate for other people. I've had multiple "cm or mm" shouting back and forth across the room conversations that have caused confusion. I've also had a few "vanishing decimal points" in drawings which are a bit more confusing in cgs than mmgs. I've grown to strongly prefer mm. False precision is always a risk. But for most things I do, mm has the correct amount of precision. (Circuit boards like tenths of mm; most small mechanical assemblies like a mm or a tenth of a mm).
