Conversion Formula
The conversion from kilometers per hour (kph) to miles per hour (mph) relies on the relationship between kilometers and miles. One mile equals approximately 1.60934 kilometers. To convert kph to mph, you divide the speed by 1.60934 or multiply by 0.621371 (which is 1 ÷ 1.60934).
This works because miles and kilometers are units measuring distance, so converting speed from one unit to another involves conversion of the distance unit while keeping the time unit constant (hour).
Example calculation:
- Given speed: 196 kph
- Multiply by conversion factor: 196 × 0.621371 = 121.850716
- Rounded result: 121.85 mph
Conversion Example
- Convert 150 kph to mph:
- Step 1: Take 150 kph.
- Step 2: Multiply by 0.621371 → 150 × 0.621371 = 93.20565
- Step 3: Rounded value is 93.21 mph.
- Convert 100 kph to mph:
- Step 1: Start with 100 kph.
- Step 2: Multiply 100 × 0.621371 = 62.1371
- Step 3: Result is 62.14 mph.
- Convert 75 kph to mph:
- Step 1: 75 kph is given.
- Step 2: Multiply 75 × 0.621371 = 46.602825
- Step 3: Rounded to 46.60 mph.
- Convert 220 kph to mph:
- Step 1: 220 kph taken.
- Step 2: Multiply 220 × 0.621371 = 136.70162
- Step 3: Rounded to 136.70 mph.

Conversion Definitions
KPH: Kilometers per hour is a unit measuring speed expressing how many kilometers are traveled in one hour. It’s used mostly outside the US for road speed limits and vehicle speeds, representing the distance covered over time using the metric system.
MPH: Miles per hour is a unit of speed indicating the number of miles traveled in one hour. It is common in the United States and the UK for speed limits and vehicle speed measurements, derived from the imperial system of units.
Conversion FAQs
Why do we multiply by 0.621371 to convert kph to mph?
The number 0.621371 represents the ratio of one mile to one kilometer; since 1 mile equals about 1.60934 kilometers, multiplying kilometers by 0.621371 converts the distance from kilometers to miles. When applied to speed, this factor directly changes kph to mph.
Can I convert mph back to kph using a similar formula?
Yes, converting from mph to kph involves multiplying the mph value by 1.60934, which is the inverse of the 0.621371 factor. This returns the speed from miles per hour to kilometers per hour by scaling the distance unit accordingly.
Is the conversion factor exact or approximate?
The factor 0.621371 is a rounded approximation of the exact ratio between miles and kilometers. While very close, small differences exist beyond the sixth decimal place. For most practical uses, this level of precision is more than enough.
Does this conversion affect time units in speed?
No, the time unit (hours) remains unchanged during conversion. Only the distance units switch between kilometers and miles. Because speed involves distance over time, converting distance units changes the numeric value but the time measurement stays the same.
Why is it useful to have a conversion chart for kph to mph?
A conversion chart provides quick access to common values without needing a calculator or remembering the exact formula. It helps drivers, travelers, and engineers compare speeds in different unit systems easily, saving time and preventing mistakes.
