Conversion Formula
The formula to convert miles per hour (mph) to kilometers per hour (kph) is:
kph = mph × 1.60934
This works because the length of 1 mile equals exactly 1.60934 kilometers. So when you multiply a speed value in miles per hour by 1.60934, you get its equivalent speed in kilometers per hour.
Example calculation:
- Start with 101 mph.
- Multiply 101 by 1.60934.
- 101 × 1.60934 = 162.54234 kph.
- Round or keep decimals as needed, here 162.5424 kph.
Conversion Example
- Convert 55 mph to kph:
- Multiply 55 by 1.60934.
- 55 × 1.60934 = 88.5137 kph.
- This means 55 mph equals about 88.5137 kph.
- Convert 75 mph to kph:
- 75 × 1.60934 = 120.7005 kph.
- So, 75 mph is approximately 120.7005 kilometers per hour.
- Convert 90 mph to kph:
- 90 × 1.60934 = 144.8406 kph.
- Therefore, 90 mph equals 144.8406 kph.
- Convert 100 mph to kph:
- 100 × 1.60934 = 160.934 kph.
- So 100 mph corresponds to 160.934 kilometers per hour.
- Convert 120 mph to kph:
- 120 × 1.60934 = 193.1208 kph.
- Meaning 120 mph is 193.1208 kph.

Conversion Definitions
mph: Miles per hour is a unit measuring speed expressing how many miles are traveled in one hour. It is mostly used in the United States and the United Kingdom to represent speed limits and vehicle speeds on roads.
kph: Kilometers per hour is a metric unit of speed showing how many kilometers are covered during one hour. It is standard in most countries and used for traffic speeds, scientific measurements, and international travel.
Conversion FAQs
Why is the conversion factor 1.60934 used to convert mph to kph?
Because one mile equals exactly 1.60934 kilometers, this value is the fixed ratio between these units. Multiplying mph by 1.60934 translates the distance covered in miles to kilometers, adapting the speed to metric units.
Can I simply double the mph value to get kph?
No, doubling mph results in an overestimation. The precise factor is 1.60934, not 2. Using 2 would give an incorrect kph value, making speeds appear faster than they are.
Does temperature or altitude affect mph to kph conversion?
The conversion between mph and kph depends only on distance units, so environmental conditions like temperature or altitude do not influence it at all.
Why does the conversion sometimes show different decimal places?
The decimal places depend on rounding preferences or display settings. More decimals provide higher precision, but for practical uses, rounding to two or three decimals is usually sufficient.
Is mph used outside the United States and UK?
While mph is most common in the US and UK, some other countries or industries may use it, but kph is generally the preferred standard worldwide for measuring speed.
