i'm using Knoppix, installed on hd,which I think makes it Debian. I have one problem which I would think affects most people in the UK. It lets me choose either "Metric" (which is not ideal because I live and work in miles, not metres and use gallons, not litres), or "Imperial" (which is not ideal because it uses Fahrenheit where I use Celsius, and insHg where I use hPa.)
Windows lets me choose the units I want for each category. I haven't (yet) found out how to do that in Linux. Is there a switch somewhere, for example to select metric + miles + gallons (Imperial, not US) + hPa?
