How do I convert MPH to KPH?

Multiply the speed in mph by 1.60934 to get km/h. For example, 70 mph x 1.60934 = 112.65 km/h. For a quick mental estimate, multiply by 1.6 or add 60% to the mph figure.

What are common European speed limits in mph?

Most European motorways are 120-130 km/h (75-81 mph). Urban areas are typically 50 km/h (31 mph) and rural roads 80-90 km/h (50-56 mph). France motorways are 130 km/h (81 mph) and Germany has sections with no limit.

Why does the UK use mph instead of km/h?

The UK retained miles per hour when most of Europe switched to metric. Road signs, speedometers, and speed limits are all in mph. However, UK cars sold since the 1970s have dual speedometers showing both mph and km/h.

Do I need to know km/h for my driving licence?

The UK driving test only uses mph. However, if you plan to drive in Europe, understanding km/h is essential for reading speed limit signs and avoiding fines.

Do I need to convert my speedometer for driving in Europe?

Most modern UK cars have both mph and km/h on the speedometer dial. If yours only shows mph, you need to convert for European speed limits. Key conversions: 30 km/h = 19 mph, 50 km/h = 31 mph, 80 km/h = 50 mph, 110 km/h = 68 mph, 130 km/h = 81 mph.
