Conversion Formula
The conversion rests on the definition of the international mile: 1 mile = 1.609344 kilometers exactly. A speed in kilometers per hour is therefore divided by 1.609344 to get miles per hour.
Since 1 kilometer = 0.621371 miles
So 130 km/h is about 81 mph
A quick mental shortcut: multiply the km/h figure by 6 and drop the last digit. 100 km/h → 600 → 60 mph, which is within 4% of the exact 62.14 mph.
Where KM/H and MPH Are Used
Kilometers per hour (km/h) is the road-speed unit in the vast majority of countries, including all of continental Europe, Canada, Australia, and most of Asia, Africa and South America.
Miles per hour (mph) remains the standard in the United States and the United Kingdom, as well as a handful of smaller territories. Rental-car drivers and travelers crossing between these systems are the most frequent km/h to mph converters.
Frequently Asked Questions
Common questions about km/h to mph conversion
How do you convert km/h to mph?
Divide the speed in kilometers per hour by 1.609344, or multiply it by 0.621371. For example, 100 km/h ÷ 1.609344 = 62.14 mph.
What is 100 km/h in mph?
100 km/h equals 62.14 mph. It is the standard highway speed limit in Canada, Australia and much of Europe.
What is 130 km/h in mph?
130 km/h equals 80.78 mph. It is the motorway limit in France, Italy and Austria and the advisory limit on the German autobahn.
Is kph the same as km/h?
Yes. "kph", "kmph" and "km/h" all mean kilometers per hour. km/h is the standard written form.
Why is the factor 1.609344?
The international mile is defined as exactly 1,609.344 meters, so one mile per hour is exactly 1.609344 kilometers per hour.
