Advice 1: How to calculate cubic meters

Often it is necessary to calculate the volume of different substances or objects in a cubic meter ofAh. It is easy to produce in that case, if it is, for example, of bricks or boards. It is sufficient to measure three spatial quantities – the length, width and height. But the situation becomes much more complicated when carrying out calculations of a liquid or relatively liquid substances (cement, water, etc.), for which you cannot use linear measurement tools. In this case, the calculation can be carried out according to the formula. You will need
• calculator, sheet of paper and a pen in his absence.
Instruction
1
Determine what kind of product do you need to translate. If it is a subject that can be measured by the meter, the definition of cubic metres will not have any problems. Is simply to multiply the value of length, width and height measured in metres of each other. For example, the length – 3 meters, height 1 meter, width – 15 meters. Example calculation – multiply 1 15 and 3. Work values – 45 cubic metres (or cubic meters).
2
Please note that you can only be known mass of the substance, for example, concrete. In this case, you should pay attention to the density of a substance when calculating the number of cubic meters.
3
Perform the following calculations in determining the volume. It is known that each substance has its own specific weight, which corresponds to the weight of one cubic decimeter or one liter (for liquids). So water has a specific gravity of 1.0 kg/dm3. This means that 1000 litres is one cubic meter. Thus, to determine the number of cubic meters, based on existing weight, you need to know the specific weight of the substance.
4
Measure cubic volume be another simple way. To do this, immerse the object whose volume in cubic meters you need to know in the water. The volume of displaced water equals the volume of the object. As the proportion of water, which was above 1.0 kg/dm3, the amount you calculate fast enough.
Note
When translating the one into the other should pay attention primarily on the density of matter, as its specific weight can be used in the calculations. In addition, the need to use measuring instruments for carrying out measurements. Can be used and the standard means. For example, the thing whose length you know. If you come across the concept of "meter", it means ordinary meter, defined in length.
Please note that it is not always simple to calculate cubic volume. Sometimes not only need to know linear (or linear) size. To determine the cubic volume of homogeneous substances without gaps may be sufficient measurements to be made. And to determine the amount of heterogeneous items between them because of their status or nature can be gaps (wood, metal objects, details, etc.), it is necessary to resort to more complex calculations using specific gravity or density of a substance and its weight.

Advice 2 : How to convert from liters to meters cubed

Liters and cubic meters measure volume. Only the meter is the international unit system SI, and a liter — no. Consider how connected these two units volume, the names of which we meet almost daily. You will need
• calculator,
• - computer with operating system Windows 7 or connecting to the Internet.
Instruction
1
Interest multiply the number of liters by 0.001. Received the product and will Express the same amount, but in cubic meters since one liter is 0.001 cubic meters.
2
In addition to this method, it is possible to transfer the units (in particular from liters to meters cubed) using converters operating in the online mode or by using a standard calculator operating system Windows XP, 7 or Vista.
3
Type in the search engine (Google, Yandex, Nigma, etc.) the Desired expression, e.g. "10 litres cubes". The search engine already has built-in conversion function.
4
Open your computer file calc.exe. Perform the necessary translation of liters into cubic meters - bar conversion of units of measurement is displayed to the right of the main panel of the calculator.
5
Interestingly, the ratio of liters and cubic meters was finally "legalized" in 1964. Until 1901, the liter was defined as one kilogram of water without additives at a pressure of 760 millimeters of mercury and a temperature of 3.98 degrees Celsius, corresponding to the maximum density of the H2O. That is a contrast to the modern liter equal to one cubic decimeter, a liter sample 1901 was 0,000028 cubic decimeter.

In the 18th century, the meter had several definitions. One of them, a meter called the length of a pendulum with a half period of the swing is 1 second, suspended in a specific location (specifically, latitude 45 degrees). The difference this meter and modern was 6 mm.
Another definition (same as before leagues and nautical mile) meter was tied to the Paris Meridian: per meter was taken a distance equal to one forty parts. This meter is almost equal to the modern (the error is negligible).
Now for the meter is made the product of a number and the wavelength emitted by the isotope krypton.
