Conversion Formula
To convert kilometers per hour (km/h) into miles per hour (pmh), you use the formula:
pmh = km/h × 0.621371
This formula works because 1 kilometer equals approximately 0.621371 miles. By multiplying the speed in km/h by this factor, you convert the distance unit from kilometers to miles, keeping the time unit consistent in hours.
Example calculation for 98 km/h:
- Start with 98 km/h.
- Multiply by 0.621371: 98 × 0.621371 = 60.894658.
- The result is about 60.8947 pmh when rounded to four decimal places.
Conversion Example
- Convert 45 km to pmh:
- Multiply 45 by 0.621371.
- Calculation: 45 × 0.621371 = 27.961695.
- Result: Approximately 27.9617 pmh.
- Convert 120 km to pmh:
- Multiply 120 by 0.621371.
- Calculation: 120 × 0.621371 = 74.56452.
- Result: About 74.5645 pmh.
- Convert 80 km to pmh:
- Multiply 80 by 0.621371.
- Calculation: 80 × 0.621371 = 49.70968.
- Result: Roughly 49.7097 pmh.
- Convert 99 km to pmh:
- Multiply 99 by 0.621371.
- Calculation: 99 × 0.621371 = 61.515729.
- Result: Approximately 61.5157 pmh.

Conversion Definitions
km: Kilometers (km) is a metric unit of distance or length, equal to 1,000 meters. Used globally for measuring long distances like between cities or countries, it is part of the International System of Units (SI) and commonly seen in transportation, geography, and science.
pmh: Miles per hour (pmh) is a unit to express speed, indicating how many miles are traveled in one hour. Primarily used in the United States and the UK, it measures speed for vehicles, weather conditions, and more. One mile equals about 1.609 kilometers.
Conversion FAQs
Why does multiplying km/h by 0.621371 give pmh?
The factor 0.621371 converts kilometers to miles because one kilometer equals approximately 0.621371 miles. Multiplying by this number changes the distance unit while keeping the time unit as hours, so km/h becomes pmh.
Can I use a rough estimate instead of 0.621371 for quick conversion?
You can use 0.62 as an approximate factor for quick mental math. For example, 98 × 0.62 = 60.76 pmh, close to the precise 60.89 pmh. Though less exact, it is suitable for quick, rough conversions.
Is converting km/h to pmh reversible without loss?
You can convert pmh back to km/h by dividing by 0.621371 (or multiplying by about 1.60934), but rounding in either step causes small errors. Exact reversibility is limited by decimal precision used.
Why do some sources use mph instead of pmh?
“mph” stands for miles per hour and is more common abbreviation. “pmh” means the same, but is less used. Both represent speed in miles per hour, so conversion results are identical regardless of abbreviation.
How accurate is the conversion factor 0.621371?
The 0.621371 factor is based on the internationally agreed definition of a mile (1,609.344 meters). It is highly accurate for everyday and scientific use, with negligible differences for practical speed conversion.
