122 km h to mph

Suppose you want to convert mph into kilometers per hour.

In this article I will show you how to convert miles per hour into kilometres per hour. Throughout the explanation below I might also call it mph to kph. They are the same thing! A miles per hour is greater than a kilometres per hour. I know that a mph is greater than a kph because of something called conversion factors.

122 km h to mph

Although the metre was formally defined in , the term "kilometres per hour" did not come into immediate use — the myriametre 10, metres and myriametre per hour were preferred to kilometres and kilometres per hour. Abbreviations for "kilometres per hour" did not appear in the English language until the late nineteenth century. The kilometre , a unit of length , first appeared in English in , [9] and the compound unit of speed "kilometers per hour" was in use in the US by Among these were the use of the symbol "km" for "kilometre". In , as part of its preparatory work for the SI , the CGPM adopted symbols for many units of measure that did not have universally agreed symbols, one of which was the symbol "h" for "hours". The SI explicitly states that unit symbols are not abbreviations and are to be written using a very specific set of rules. Danloux-Dumesnils [34] provides the following justification for this distinction:. It has already been stated that, according to Maxwell, when we write down the result of a measurement, the numerical value multiplies the unit. Hence the name of the unit can be replaced by a kind of algebraic symbol, which is shorter and easier to use in formulae. This symbol is not merely an abbreviation but a symbol which, like chemical symbols, must be used in a precise and prescribed manner. SI is also the preferred system of measure in academia and in education. During the early years of the motor car, each country developed its own system of road signs. Many countries have since signed the convention and adopted its proposals. Speed limits signs that are either directly authorised by the convention or have been influenced by the convention are shown below:. In the EU published a directive [40] overhauled in [41] to take British and Irish interests into account that required member states to abandon CGS-based units in favour of SI.
