Google Maps shows a 5 mile route — how many km is that?
5 miles is about 8.05 km, handy when a US or UK map shows distance in miles and you need the actual kilometers to plan a drive or walk.
A US highway speed limit of 65 mph — roughly how fast is that in km/h?
65 × 1.609344 is about 104.6, so 65 miles converts to roughly 104.6 km — the same mile-to-km ratio applies to speed, which is handy for understanding speed limit signs while driving in the US or Canada.
