Conversion Formula
The formula to convert miles per hour (mph) to kilometers per hour (kmph) is:
kmph = mph × 1.60934
This works because 1 mile equals 1.60934 kilometers. Therefore, multiplying the speed in miles per hour by that factor converts it into kilometers per hour.
Example:
- Start with 71 mph.
- Multiply 71 by 1.60934.
- 71 × 1.60934 = 114.26314 kmph.
- Rounded to four decimal places, it becomes 114.2632 kmph.
Conversion Example
Here are some example conversions from mph to kmph, showing steps:
- 50 mph
- Multiply 50 by 1.60934.
- 50 × 1.60934 = 80.467 kmph.
- The result is 80.467 kmph.
- 85 mph
- Multiply 85 by 1.60934.
- 85 × 1.60934 = 136.7939 kmph.
- This equals roughly 136.7939 kmph.
- 60 mph
- Multiply 60 by 1.60934.
- 60 × 1.60934 = 96.5604 kmph.
- So, 60 mph is 96.5604 kmph.
- 30 mph
- Multiply 30 by 1.60934.
- 30 × 1.60934 = 48.2802 kmph.
- Thus, the speed is 48.2802 kmph.

Conversion Definitions
mph: Miles per hour (mph) is a unit of speed measuring the number of miles traveled in one hour. Used mainly in the United States and United Kingdom, it’s common for expressing speed limits and vehicle speeds on roads.
kmph: Kilometers per hour (kmph) is a metric unit of speed showing how many kilometers are covered in one hour. It’s widely used internationally, especially in countries adopting the metric system for measuring velocity and speed.
Conversion FAQs
Why does multiplying by 1.60934 convert mph to kmph?
Because one mile equals 1.60934 kilometers, multiplying mph by this factor converts miles into kilometers while keeping the time unit as hours. So, the speed is converted correctly without changing the time scale.
Can I use a simpler number for conversion?
Sometimes 1.6 is used for quick estimates, but it’s less accurate. Using 1.60934 provides a more precise conversion, especially useful when decimals matter.
Does this conversion affect vehicle speed limits?
The conversion helps when comparing speed limits in mph and kmph. For example, 71 mph equals about 114.26 kmph, so knowing this helps drivers adjust to different countries’ speed rules.
Is the conversion factor always constant?
Yes, 1 mile is always 1.60934 kilometers exactly by definition, so the factor doesn’t change. This means conversion stays consistent no matter the speed value.
How to convert kmph back to mph?
To convert kmph to mph, divide the kmph value by 1.60934. This reverses the multiplication and gives the speed in miles per hour.
