Advice 1: How to convert kilometers per square kilometers

When solving practical problems sometimes we have to translate each other quite heterogeneous units. For example, liters often translated into kilograms and miles into square kilometers. However, in each case, the solution of such problems usually is not difficult. It is only necessary to grasp the essence of the task and the use of additional (accompanying) information.

To convert kilometers per square kilometers, it is necessary to clarify what is being measured or calculated in these units. Most likely, it will be such features as area and linear length of the object. As a rule, in such cases it is known the width of the object, and the length or area may vary within considerable limits.

To translate kilometers square kilometers in the measurement of the road, simply multiply the length of the road on its width. The width of the road previously also put in the miles. Since the road width is typically specified (measured) in meters, simply divide the width of the road (in meters) by 1,000.If the width of the road is unstable, it is put in square miles of each area having the same width. Then fold the resulting square. If high accuracy is unimportant, take as the width of the road its average width.If the road is Federal highway, find its width in the relevant handbooks (such as atlases motorists). For approximate calculations the width of the Central artery take is equal to 8 meters (0,008 km) is the average width of the route the Federal highways.

In order to know how many square kilometres and contains several kilometers of construction material (e.g., linoleum or Wallpaper), then multiply by the width of the material (converted to kilometers) of linear length, also expressed in kilometers. If the materials are supplied in rolls (pieces) of different widths, then multiply by the appropriate width running the length of each roll and fold the resulting works.

Advice 2: How to convert square meters to square kilometers

To be able to specify the size of a limited section of the plane, mathematicians introduced the definition of "surface area". To quantify this characteristic at different times and in different countries used different units. Today, most countries use recommended in the international system, SI unit of area measurement is square meters , and a multiple of their size, including square kilometers.
How to convert square meters to square kilometers

Divide the resulting measurement in square meters the size of a surface in a million to change the value in square kilometers. This conversion factor is derived directly from the name of the unit of measurement is "square kilometer". The prefix "kilo" in the SI system is used to refer to thousandfold increase in the unit - which is a word derived from the Greek meaning thousand. And the word "square" indicates that this thousand be raised to the second power, i.e. multiplied by itself. One thousand squared, will result in a unit with six zeros is a million.

Move the decimal point in the original value six positions to the left to convert square meters into square kilometers. This operation does not even require to make any calculations.

If there are problems with conversion, then use the online calculators to convert units of area measurement - in the Internet you can find a lot of. For example, go to the page http://convertworld.com/ru/ploshhad/Квадратные+meters.the html in the box under "I want to" specify the initial size in meters. In the drop-down list next to the field "square meters" is selected by default, and in the next drop-down list to specify the desired accuracy of the result of the conversion. Immediately after that, opposite to "square Kilometer", you will see the equivalent of the initial value, expressed in square kilometers.

Search engines also know how to convert units of area measurement. To download, for example, the home page of the Google search engine and type the appropriate query. For example, if you want to translate 1587 m?, the query could look like this: "1587 square meters in square kilometers". The Google calculator will recalculate and display the result: "1587 (square meters) = 0.001587 square kilometre".
