However, there were quite a few myths surrounding speeds at which human beings could travel. With the advent of roads during the early 19th century speeds increased quite significantly.
This made the job of coming out with time-table that much easier and simpler. To make this possible it was decided to make use of the miles per hour to calculate the time taken by these rail coaches to travel from one city/town to another city/town. This was done because running over long distances in stages required following a reasonably accurate timetable. It was used to measure the speed with which regular stage coaches travelled. It would be pertinent to mention here that miles per house perhaps came into existence and was used during the 18th century. Today in most of these countries, except perhaps a few, whenever speed and distances are measured in imperial systems, they take the trouble to convert it into metric system of calculating speed vis-à-vis distance covered. This could have happened sometime during the second half of the twentieth century. However, as time passed on the imperial system was replaced with the metric system in most of the above countries. 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. 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.Īs mentioned above, this is commonly used in countries like the United Kingdom and the USA. 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. 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, in most American and European nations, people are more aware of mile rather than kilometer. On the other hand one mile is equal to 1.609 kilometers. Hence if we are riding a bike which travels at 60 mph we are referring to the fact that in one hour the bike would able to cover 60 miles and perhaps 120 miles in two hours if it travels at the same speed.Īpart from miles, kilometer is also used commonly.ġ kilometer is equal to 0.6213 miles and this method of time and distance is also used. When we talk about a mile or a kilometer we are basically referring the distance that one is able to cover within a specified time of one hour. Hence we will try and spend some time knowing more about the origins of the various measuring yardsticks as far as time and distance are concerned. While we use them quite regularly, we need to know what exactly the history is behind this. It is about calculating the distance traveled over a period of time.ĭistance is covered measured by certain time-tested methods and the most common terms used are miles, kilometers and so on. When we take this logic of movement forward we come to the world of time and distance. Hence the only thing that is constant about life is movement. The universe also is moving around the sun and the universe is also in orbit. It revolves around itself and around the sun. The final formula to convert 220 MPH to KMH is: = 220 x 1.61 = 354.2 Miles/hour to Kilometers/hour formula: = Miles x 1.61
