About this conversion

Miles per hour to km/h is needed whenever UK or US drivers travel to continental Europe, or vice versa. The UK uses mph on all road signs; every other EU country and most of the world uses km/h. Speed limit quick reference: UK 30 mph = 48 km/h (urban), 60 mph = 97 km/h (rural), 70 mph = 113 km/h (motorway). Germany autobahn: recommended 130 km/h = 81 mph. USA interstate: 70 mph = 113 km/h. France: 130 km/h motorway = 81 mph, 80 km/h rural = 50 mph. Italy: 130 km/h motorway = 81 mph. Converting is critical for rental cars abroad — a speedometer showing mph in a country with km/h signs can lead to inadvertent speeding.
