I prefer the metric system but have had to learn imperial due to being in the US. The only thing that bothers me is the date format. Prefer month/date/year (or y/m/d). Western calendars are organized by year/month/date.
For me, writing 4/24 gives more information up front (time of year) than 24/4 (time of month).
Year.Month.Day also just makes it so you can automatically sort files on a disk by name and get them in chronological order.
But yeah really wish we would move over to metric in the US regardless. Especially for measurement..... Heck we technically are using it too but just for "Trade and Commerce"
