There are several ways to calculate the volume in liters. If you are faced with liquid, which is Packed in the bottle, there is always this volume is specified in liters. However, there are containers on which the volume specified in cubic meters. From elementary school it is known that 1 m^3 = 1000 L. Accordingly, if you need to find the volume of any container in liters, you should multiply the set value in cubic meters to 1/1000:a (l) = b(m^3) * 0,001.Thus, you will be able to calculate the volume in liters for a given volume measured in m^3. It is a simple transfer from one unit to another SI. However, if you volume is still unknown, will need to find it in meters and then convert to liters.

Suppose you know only the mass of the liquid in the container. With the help of simple formulas, which is known from school physics course, it is possible to find the volume. The formula is:p = m/V where m is the mass of the fluid, p is the fluid density.The density of the liquid you can find, on the basis of tabular data. In all textbooks of physics the density of liquids, including water, oil, kerosene, mercury, etc., Respectively, the volume is:V= m/p ( m^3).Further, also according to the scheme V(l) = V(m^3) * 0,001.

If you do not know neither the volume nor the mass of the containers, but it is clear stereometric figure, for example, the cylinder volume can be found in two stages: first, it is necessary to conduct experimental measurement, and then algebraic calculations. For this you need to measure the base radius of the cylindrical container and its height. The volume of such containers is equal to:V= NR^2 * H where R is the radius of the base of the container, H - height ( m ^3).Similarly, V(l) = V(m^3) * 0,001.
