Miles Per Hour to Kilometers Per Hour Converter
One of the most widely measured values in our daily life is speed. Whether it is driving a car or monitoring fitness progress, understanding the speed at which something is travelling can be important in terms of safety, planning, and performance. But not all countries measure speed in the same unit. The common measure of speed in the United States and the United Kingdom is miles per hour (mph). Speed in most other countries is known in kilometers per hour (km/h).
Conversion between the two units comes in handy when one is traveling, reading international documents, using a GPS device,s or comparing specifications of different vehicles.
Learning About the Units
Miles per hour (mph) is defined as the distance covered in one hour.
The speed in kilometers per hour (km/h) is the distance in kilometers moved in an hour.
The mile is greater than the kilometer, the value of the speed will occupy a bigger value in km/h compared to mph. This variation is attributed to the conversion factor between kilometers and miles.
Miles Per Hour to Kilometers Per Hour Converter Conversion Formula
To convert miles per hour to kilometers per hour, multiply the speed by 1.60934.
Formula:
km/h = mph × 1.60934To convert kilometers per hour to miles per hour, divide the value by 0.621371.
Formula:
mph = km/h ÷ 1.60934This conversion factor is fixed and applies to all speed calculations between these two units.
Example: Converting mph to km/h
If you’re driving at 65 mph and want to know your speed in kilometers per hour:
65 × 1.60934 = 104.61 km/h
So, you’re driving at approximately 104.61 km/h. This is especially helpful when traveling in countries where road signs and speed limits are listed in kilometers per hour.
Where This Conversion Is Used
This type of conversion is essential in:
- Travelling abroad: When you rent a car abroad speed limits might be in km/h.
- Car characteristics: Speed or performance may be displayed in both systems in cars marketed worldwide.
- Fitness and sports: The apps and devices can be set to default km/h or mph depending on the location.
- Education and science: Pupils are frequently required to transform rates in physics or math difficulties.
