Conversion Formula
The formula to convert kilometers per hour (km/h) to miles per hour (pmh) is:
pmh = km × 0.621371
This formula works because 1 kilometer equals approximately 0.621371 miles. So by multiplying the speed in kilometers by this conversion factor, you get the equivalent speed in miles.
For example, converting 98 km/h to pmh step-by-step:
- Start with 98 kilometers per hour.
- Multiply 98 by 0.621371: 98 × 0.621371 = 60.894358.
- Round the result to a reasonable decimal place: 60.8944 pmh.
Conversion Example
- Convert 75 km/h to pmh:
- Multiply 75 × 0.621371 = 46.602825.
- Result: 46.6028 pmh.
- Convert 110 km/h to pmh:
- Multiply 110 × 0.621371 = 68.35081.
- Result: 68.3508 pmh.
- Convert 85 km/h to pmh:
- Multiply 85 × 0.621371 = 52.816535.
- Result: 52.8165 pmh.
- Convert 100 km/h to pmh:
- Multiply 100 × 0.621371 = 62.1371.

Conversion Definitions
km (kilometer): A kilometer is a unit for measuring distance in the metric system. Equal to 1,000 meters, it’s used worldwide to quantify length, especially for longer distances like roads, running tracks, or geographical spans. It’s part of the International System of Units (SI).
pmh (miles per hour): Miles per hour measures speed in the imperial system, indicating how many miles are traveled in one hour. Common in the US and UK for speed limits and vehicle speeds, it is based on the mile, which equals 5,280 feet or about 1,609.34 meters.
Conversion FAQs
Why does multiplying by 0.621371 convert km/h to pmh?
The number 0.621371 is the conversion factor between kilometers and miles. Since 1 km equals 0.621371 miles, multiplying a speed in km/h by this value changes the unit to miles per hour, giving you the correct equivalent speed.
Can I use this conversion factor for all speeds?
Yes, the factor 0.621371 applies for any speed measured in kilometers per hour to convert to miles per hour, regardless of the speed’s size. The relationship between kilometers and miles remains constant.
Is there a quick way to estimate the conversion without a calculator?
You can approximate by remembering 1 km ≈ 0.62 miles. Multiplying by 0.62 gives a close estimate but less precise than 0.621371. For rough conversions, this shortcut works well in everyday use.
Why do some sources use different numbers for the conversion?
Some sources round the conversion factor to 0.62 or 0.621 for simplicity, instead of using 0.621371 exactly. This rounding causes small differences but usually doesn’t affect practical results much.
What is the difference between pmh and mph?
They both mean miles per hour, but “pmh” stands for “per mile hour,” less commonly used. “mph” is the standard abbreviation in most English-speaking countries for miles per hour.
