# 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.
2
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 in square meters

Square meters are a standard unit of area. But in the tasks there are other units of measurement. Therefore there is a need to translate the value of the square of the specified units of area measurement in square meters.
Instruction
1
Make sure that you want to transfer in square meters the area, and not any other value: volume, length, mass, speed, etc.
2
Let us consider what needs to be done to put the value in square meters.If there is a square kilometers, comnote the number 10^6 (10 to the 6th degree, 1000000) to get square meters.If set, deci squaremeters, divide by 10^2.If set to Santi squaremeters, divide by 10^4.If set to square Millimeters, divide by 10^6.If set to square micrometers, divide by 10^12.If set to square nano -meters, divide by 10^18.If set Pico squaremeters, divide by 10^24.
3
If the area is given in hectareAh, comnote 10^4, and get the area in square metres.If the area specified in Arah, comnote 10^2.
4
Having the area value in square meters, you can continue working with the area.
Before solving the problem translate all values into a single standard system of units (SI). Sometimes this procedure helps to even see the key to solving the problem.

# Advice 3: 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.
Instruction
1
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.
2
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.
3
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.
4
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".

# Advice 4: How to translate miles to kilometers

Mile as the unit of measurement passed or forthcoming way first appeared in Ancient Rome. With time it is widespread, but the distance was defined this concept in different regions, differed very significantly from 580 meters to 11300. In the 18th century in Europe there was more than four dozen definitions of this unit, but after the transition the majority of countries on the metric system it was replaced by the kilometer. Today, with the conversion of miles to kilometers, as a rule, mean British or American mile their numerical expressions are the same.
Instruction
1
Divide the distance given in miles, 1,609344, as in every British or American mile contains 1 mile of 609 meters 34 centimeters and 40 millimeters. For example, the distance of 150 miles meets 241,4016 km.
2
If you need to convert to kilometers number of miles a non-circular computation "in mind" can be replaced with a calculator. If you have access to a computer, use the built-in Windows operating system by the application of this kind. To access it, press the Windows key and start typing the word calculator. The OS will guess what you want, and after the second letter on the top line with the results of her meditations link will appear on your desired program. Press Enter and the system will run this application.
3
Clicking on the buttons in the calculator interface or by pressing the appropriate keys, enter the distance in miles, press with a forward slash - "slash" - type 1,609344. Then press Enter and see the result of the conversion of miles to kilometers.
4
To perform calculations of the previous step in modern versions of this calculator is not necessary - it is built-in currency Converter, which provides and transfer miles to kilometers. To use the Converter, press Ctrl + U or select the "unit Conversion" under "View" menu of the calculator.
5
Fields for entering values of the Converter are placed on the additional panel. Select in the top drop-down list of this panel, the string "Length", in the same list in the lower part set to "Kilometers", and arranged between the set value of "Mile". Then enter the initial number in the box below with a short inscription "From". The result of the conversion you will see in the field with the even more concise "b"designation.
