Frequently Asked Questions
How do I convert mph to km/h?▼
Multiply mph by 1.60934 to get km/h. A quick mental shortcut: multiply by 1.6 (close enough for everyday use). For example, 60 mph × 1.6 = 96 km/h (actual: 96.56). For km/h to mph, multiply by 0.6214, or use the rough shortcut of dividing by 1.6.
Which countries use mph?▼
Only three countries officially use miles per hour for road signs: the United States, the United Kingdom, and (in some contexts) Myanmar. Almost every other country uses kilometers per hour (km/h). Canada uses km/h but many Canadians think in mph due to proximity to the USA.
Is the German Autobahn really unlimited speed?▼
Some sections of the German Autobahn have no statutory speed limit ('freie Fahrt'), but these sections are shrinking. About 30% of the Autobahn now has permanent limits, and more have temporary limits. The recommended (advisory) speed on unlimited sections is 130 km/h (81 mph). Driving faster than the advisory speed can affect liability in accidents.
What is the fastest legal speed limit in the world?▼
The UAE has some roads with 160 km/h (99 mph) limits. Poland has some motorways at 140 km/h. Germany's unlimited Autobahn sections allow any speed. In the USA, some rural Texas highways allow 85 mph (137 km/h). The Isle of Man has no national speed limit on non-built-up roads.
