About KPH (km/h) and MPH
KPH (kilometers per hour, more often written km/h or kmh) is the global standard, used by every country except the United States, the United Kingdom, and a few others. MPH (miles per hour) covers about 5 percent of the world road traffic. The conversion is exact: 1 km equals 0.621371 miles, so 1 kph equals 0.621371 mph. To approximate quickly in your head, divide by 1.6 or multiply by 0.6. For an exact figure, use the calculator above or the table below. Common road speeds: 50 kph = 31 mph, 80 kph = 50 mph, 100 kph = 62 mph, 130 kph = 81 mph.
