To have an opportunity to specify the size of any limited site of the plane, mathematicians entered determination of "surface area". Different units were at different times and in different countries applied to quantitative expression of this characteristic. Today the majority of the countries use the area units of measure recommended in the international SI system - square meters and multiple to them sizes, including square kilometers.
Instruction
1. You divide squaremetersthe surface size received as a result of measurement in into one million to transfer this value to square kilometers. This coefficient of the translation flows directly from the name of unit of measure - "square kilometer". The kilogram prefix in the SI system is used for designation of thousandfold increase in initial unit - this word comes from the Greek definition thousands. And the word "square" indicates that this one thousand should be built in the second degree, that is to increase by itself. Thousand squared will give as a result unit with six zero - one million.
2. Transfer a decimal comma in initial size to six categories to the left to transfer square meters to square kilometers. This operation does not even demand to make any calculations.
3. If there are difficulties with recalculation, then use online calculators for converting of units of measure of the area - they can be found in the Internet much. For example, pass to the http://convertworld.com/ru/ploshhad/Квадратные+метры.html page, in the field under the inscription "I Want to Translate" specify initial size in meters. In a drop-down list near this field "square meters" are chosen by default, and specify the accuracy of result of converting necessary to you in the following drop-down list. Right after it opposite to the inscription "Kilometer Square" you will see the equivalent of initial size expressed in square kilometers.
4. Search engines are able to convert area units of measure too. Load, for example, the homepage of Google search engine and enter the corresponding inquiry. Let's tell if it is required to transfer 1587 m?, the inquiry can look so: "1587 square meters in square kilometers". The calculator of Google will make recalculation and will display result: "1587 (sq.m) = 0.001587 quarter kilometer".
