Conversion Formula
To convert from miles per hour (mph) to kilometers per hour (km/h), multiply the speed value by 1.60934. This number represents how many kilometers are in a mile. Since 1 mile equals 1.60934 kilometers, multiplying mph by this factor converts it to km/h.
Example calculation:
- Given speed = 155 mph
- Multiply by 1.60934: 155 × 1.60934 = 249.4487 km/h
- So, 155 mph = 249.4487 km/h
Conversion Example
- Convert 100 mph to km/h:
- Multiply 100 by 1.60934
- 100 × 1.60934 = 160.934 km/h
- The result is 160.934 km/h
- Convert 75 mph to km/h:
- Multiply 75 by 1.60934
- 75 × 1.60934 = 120.7005 km/h
- So, 75 mph equals 120.7005 km/h
- Convert 50 mph to km/h:
- Multiply 50 by 1.60934
- 50 × 1.60934 = 80.467 km/h
- Therefore, 50 mph is 80.467 km/h
- Convert 120 mph to km/h:
- Multiply 120 by 1.60934
- 120 × 1.60934 = 193.1208 km/h
- 120 mph converts to 193.1208 km/h

Conversion Definitions
mph: Miles per hour (mph) is a unit of speed expressing the number of miles traveled in one hour. It is commonly used in the United States and the United Kingdom to measure speed, especially for vehicles and road speed limits.
km: Kilometer (km) is a metric unit of length equal to 1,000 meters. It is used worldwide to measure distances, especially in most countries outside the United States. One kilometer equals approximately 0.621 miles.
Conversion FAQs
Why does multiplying mph by 1.60934 convert it to km/h?
Because one mile equals exactly 1.60934 kilometers, multiplying the speed in miles per hour by this conversion factor converts the distance traveled in miles into kilometers, giving the speed in kilometers per hour. This conversion is simple multiplication without any other operations needed.
Can I convert mph to km/h by dividing instead of multiplying?
No, dividing by 1.60934 will convert km/h to mph, not the other way around. To convert mph to km/h, you must multiply by 1.60934 because the kilometer is larger than the mile, so the number gets bigger when converting mph to km/h.
Is the conversion factor 1.6 or 1.60934?
The exact conversion factor is 1.60934. Sometimes people round it to 1.6 for simplicity, but using 1.60934 provides more accurate results, especially for precise speed calculations.
Does converting mph to km/h affect the actual speed?
No, converting between mph and km/h only changes the units used to express speed. The actual speed does not change, just the measurement scale differs between miles and kilometers.
Are mph and km/h used interchangeably worldwide?
No, mph is mostly used in the United States and a few other countries, while km/h is the standard unit of speed in most countries worldwide, especially those using the metric system.
