Conversion Definitions
kph: Kilometers per hour (kph) is a unit measuring speed according to how many kilometers are traveled in one hour. It is widely used in countries adopting the metric system, measuring the velocity of vehicles or any moving object over time.
mph: Miles per hour (mph) measures speed by counting the number of miles covered in an hour. Common in the United States and United Kingdom, mph is used to indicate speeds on roadways, in aviation, and other transportation sectors.
Conversion FAQs
Why multiply by 0.621371 to convert kph to mph?
The number 0.621371 represents how many miles are in one kilometer. Multiplying by this factor changes the distance unit from kilometers to miles, without affecting the time unit. This conversion factor ensures the speed is correctly expressed in mph.
Can I convert mph back to kph using the same number?
No, converting from mph to kph uses the reciprocal factor, which is approximately 1.60934. So, to convert mph to kph, multiply the mph value by 1.60934, not 0.621371.
Does converting speed affect time measurement?
Speed conversion changes only the distance unit, not the time. Both kph and mph measure how far something moves per hour, so the time remains constant, only distance changes from kilometers to miles or vice versa.
Is there rounding error in conversions?
Yes, because the conversion factor 0.621371 is rounded to six decimal places, some small rounding errors occur, especially with large values. However, for practical use, this precision is sufficient.
Why do some speedometers show both kph and mph?
Vehicles sold in multiple countries may display both units to comply with local regulations or user convenience. This allows drivers to understand speed limits regardless of the measurement system used in the country they are driving.
