Apart from miles, kilometer is also used commonly. On the other hand one mile is equal to 1. However, in most American and European nations, people are more aware of mile rather than kilometer. The modern abbreviation for mile is mi and this has been brought in to avoid confusion when one refers to metric meter which has an abbreviation of m. However, it would be pertinent to mention that mil is still not very widely used and majority is still comfortable using either miles or mph. It would be pertinent to mention here that when we talk about miles per hour or MPH we are referring to a unit of speed which uses the imperial system of units.
Not so long ago it also was used in all the other major English speaking nations of the world including nations such as South Africa, New Zealand, Australia and Canada.
However, as time passed on the imperial system was replaced with the metric system in most of the above countries. This could have happened sometime during the second half of the twentieth century. It would be pertinent to mention here that miles per house perhaps came into existence and was used during the 18th century. It was used to measure the speed with which regular stage coaches travelled. This was done because running over long distances in stages required following a reasonably accurate timetable.
This made the job of coming out with time-table that much easier and simpler. With the advent of roads during the early 19th century speeds increased quite significantly. However, there were quite a few myths surrounding speeds at which human beings could travel. There was a huge fear amongst people that traveling beyond 20 mph could lead to suffocation and asphyxiation.
However, with civilization and with better knowledge and information this myth was dispelled. Soon there were trains which were traveling at around 50 miles per hour and passengers not only survived this speed but they also enjoyed it quite a bit.
The myth about speed and human endurance took some time die down.
