Conversion Formula
The formula to convert miles per hour (mph) into kilometers per hour (kmph) is:
kmph = mph × 1.60934
This works because one mile equals exactly 1.60934 kilometers. So, to find the equivalent speed in kilometers per hour, you multiply the number of miles per hour by 1.60934.
For example, converting 71 mph:
- Start with 71 mph.
- Multiply by 1.60934: 71 × 1.60934 = 114.26314 kmph.
- Rounded to 4 decimal places, this is 114.2632 kmph.
Conversion Example
- Convert 50 mph to kmph:
- 50 × 1.60934 = 80.467 kmph.
- So, 50 mph equals 80.467 kmph.
- Convert 88 mph to kmph:
- 88 × 1.60934 = 141.62192 kmph.
- Therefore, 88 mph equals 141.622 kmph (rounded).
- Convert 60 mph to kmph:
- 60 × 1.60934 = 96.5604 kmph.
- Thus, 60 mph is 96.5604 kmph.
- Convert 72.5 mph to kmph:
- 72.5 × 1.60934 = 116.87665 kmph.
- Hence, 72.5 mph equals approximately 116.877 kmph.

Conversion Definitions
mph: Miles per hour (mph) is a unit measuring speed or velocity, indicating how many miles are traveled in one hour. It is widely used in the United States and the United Kingdom for road speed limits and vehicle speeds. One mile equals 5,280 feet or 1,609.34 meters.
kmph: Kilometers per hour (kmph) measures speed by showing how many kilometers are covered within one hour. Used globally, especially in metric system countries, it helps expresses velocity in standard metric units. One kilometer equals 1,000 meters or approximately 0.62137 miles.
Conversion FAQs
Why is the factor 1.60934 used to convert mph to kmph?
The factor 1.60934 represents the exact number of kilometers in one mile. Since speed is distance over time, converting miles to kilometers requires multiplying the mph value by this exact ratio to get the correct kmph figure.
Can I use a simple number like 1.6 for quick conversions?
Using 1.6 as a multiplier is an approximation that gives a near value but can introduce small errors. For accurate conversions, especially in technical contexts, 1.60934 is preferred to maintain precision.
Does converting kmph back to mph use the same factor?
No, converting kilometers per hour to miles per hour requires dividing the kmph value by 1.60934, because you reverse the original multiplication to return to miles per hour units.
How does temperature or weather affect the conversion?
Temperature or weather do not affect the conversion between mph and kmph because the conversion is a fixed ratio based on distance units. Environmental factors might affect actual speed, but not the unit conversion itself.
Is there a difference between kmph and kph?
Both kmph and kph mean kilometers per hour and are used interchangeably. The abbreviation kmph is more explicit, but kph is widely accepted and understood the same way.
