Over decades of its existence, mankind has invented a lot of physical quantity measurement unit systems. Take at least such physical quantity as length. It was measured by different units such as soles, elbows, sazhens, inches, feet, meters, yards...

But, as in many cases some traditional national measurement systems, for example, the English system, are yet widespread, very often there is a need for physical quantity recalculation from one system to another. Such a need also occurs in case of reading old books, historical works, where measurement units are often given in accordance with those epochs and countries about which these books tell.
