There are several ways to calculate the volume in liters .If you encounter a fluid that is packaged in a bottle, there is always the amount specified in liters .However, there are containers in which the volume specified in cubic meters.From elementary school known that 1 m ^ 3 = 1000 liters.Accordingly, if you need to find the volume of a tank in liters , you have to multiply the set value in cubic meters per 1/1000: a (l) = b (m ^ 3) * 0,001.Takim way, you can calculate the volume liters in a given volume, measured in m ^ 3.This is a simple transfer from one unit to another SI.However, if the amount is still unknown to you, you will find it in the first meters, and then convert to liters.

Suppose you know only the mass of the liquid in the
container.Using a simple formula, which is known from school physics course, we can find the volume.The formula looks like this: p = m / V, where m - mass of the fluid, p - density of liquid zhidkosti.Plotnost you can find, on the basis of the table data.In all physics textbooks given density of liquids, including water, oil, kerosene, and mercury t.d.Sootvetstvenno volume equals: V = m / p (m ^ 3) Next, as the scheme, V (n) =V (m ^ 3) * 0,001.

If you know neither the volume nor the weight of the container, but it is clear stereometric figure, such as a cylinder, the volume can be found in two stages: first, it is necessary to carry out experimental measurements, and then - algebraic calculations.To do this you need to measure the radius of the base of the cylindrical container and its height.The volume of such containers will be equal to: V = πR ^ 2 * H, where R - radius of the base of the container, H - height (m ^ 3) Analogous, V (l) = V (m ^ 3) * 0,001.
