The Kilometers per Hour to Miles per Hour Converter converts speed from km/h to mph using the exact factor 1 mile = 1.609344 km. This converter is essential for anyone traveling between countries that use different speed measurement systems.
Kilometers per hour is the speed unit used in most of the world, appearing on road signs, car speedometers, and weather reports in Europe, Asia, Africa, South America, and Australia. Miles per hour is used in the US, UK, and Myanmar.
Understanding this conversion is critical for safe driving abroad. European speed limits of 130 km/h, 120 km/h, and 50 km/h translate to approximately 81 mph, 75 mph, and 31 mph respectively.
Our converter also provides meters per second for scientific and engineering applications.
The formula: mph = km/h ÷ 1.609344 (exact). For meters per second: m/s = km/h ÷ 3.6 (since 1 km = 1000 m and 1 hour = 3600 s). Both are exact conversions.
European speed limits in mph: 30 km/h = 18.6 mph (school zones), 50 km/h = 31.1 mph (cities), 100 km/h = 62.1 mph (rural), 130 km/h = 80.8 mph (motorways).

130 km/h = 80.8 mph — European motorway limit
100 km/h = 62.14 mph.
Divide by 1.609344, or multiply by 0.6214 for a quick estimate.
120 km/h = 74.56 mph.
200 km/h = 124.27 mph — extremely fast, typical of sports cars or bullet trains.
The advisory speed limit on the German Autobahn is 130 km/h (80.8 mph), but many sections have no enforced limit.
50 km/h = 31.07 mph — a standard European urban speed limit.
1 km/h = 0.2778 m/s (1000 m ÷ 3600 s).
The main numbers on a metric speedometer show km/h. Some also show mph on an inner scale.
A brisk walk is about 5-6 km/h (3.1-3.7 mph).
The fastest wind gust recorded was 408 km/h (253 mph) at Barrow Island, Australia in 1996.
