It might surprise you to know that, as an engineer, I have spent virtually my entire career working in metric units. When I go to the supermarket, I'm used to buying food by the pound or ounce, and I still think miles per hour when I'm driving my car (but there is something fun about those 'Speed Limit 120' signs on Canadian freeways, isn't there?). I'm not sure what it says that soft drinks by the liter are pretty universally accepted - but when our local dairy tried to introduce 4-liter jugs of milk, it flopped spectacularly.
But when I go to work, it's all millimeters, and kilograms, and Newtons and Megapascals, and all that happy stuff, and if someone tries to talk pounds, or inches, or psi, I mentally convert them back to metrics to get back in my 'comfort zone'.
Anyway, being an engineer, when I see stuff like what you'll see below, it probably amuses me out of all proportion. This is what happens when engineers try to have fun, I guess. . .
