Or in miles. How can you calculate the total road length for a country. Or a continent, or a city, etc etc I installed Qgis and learned to play a little with it.

Or calculate the lenght of all the roads. So i can download once per week and do a query, so i can tell to people that this week we have added 200 km more or roads.
