The converted speed of 15 kph equals approximately 9.32 mph.
This conversion is done by multiplying the kilometers per hour value with a factor of 0.621371, because 1 kilometer per hour equals about 0.621371 miles per hour. So, multiplying 15 by 0.621371 gives the mph equivalent.
Conversion Result and Explanation
When converting 15 kilometers per hour to miles per hour, you multiply 15 by 0.621371. This gives approximately 9.32 mph. The reason behind this is that the mile is longer than the kilometer, so the mph value is less than the kph value. This simple multiplication provides an accurate conversion.

Conversion Formula
The formula to convert kilometers per hour to miles per hour multiplies the kph value with 0.621371. This factor is derived from the fact that 1 kilometer is approximately 0.621371 miles. For example, if you have 20 kph, multiplying 20 by 0.621371 results in 12.42742 mph. This method works because it adjusts for the difference in distance units, ensuring accurate conversion.
Conversion Example
- Convert 10 kph to mph:
- Multiply 10 by 0.621371
- 10 × 0.621371 = 6.21371 mph
- Convert 25 kph to mph:
- Multiply 25 by 0.621371
- 25 × 0.621371 = 15.534275 mph
- Convert 50 kph to mph:
- Multiply 50 by 0.621371
- 50 × 0.621371 = 31.06855 mph
- Convert 5 kph to mph:
- Multiply 5 by 0.621371
- 5 × 0.621371 = 3.106855 mph
- Convert 30 kph to mph:
- Multiply 30 by 0.621371
- 30 × 0.621371 = 18.64013 mph

Conversion Definitions
kph
Kilometers per hour (kph) measures how many kilometers are traveled in one hour. It is a metric speed unit used mainly outside the United States, especially in countries that use the metric system for distance measurement and speed regulations.
mph
Miles per hour (mph) indicates how many miles are covered in one hour. It is a customary speed measurement used mainly in the United States and the United Kingdom, where distances are often measured in miles and speed limits are expressed in mph.
