What is Unit of Volume?
Unit of Volume is the measurement of the amount of fluid or space in a container. Unit of any physical quantity refers to a standard amount of the quantity chosen so that further measurements can be expressed relative to this quantity.
Unit of volume depends directly on the unit of length chosen while calculating volume of three-dimensional bodies. As SI unit of length is metre (m), the SI unit of volume becomes cubic metre (m3).
While defining capacity of vessels in litres or gallons, we use the relation that 1000 litre capacity equals to the space occupied by a cube having side length equal to 1 m. In other words, 1000 litre = 1 cubic metre of the volume.
Dimensional Formula for Volume
There are different formula for calculating volume of different three-dimensional shapes, but dimensional formula of any physical quantity remains same irrespective if the formulae available to find value of the quantity.
Therefore, let us find the dimensional formula for volume by using the formula to find volume of a cube.
Volume of a cube, V = a3, where a is the length of side of the cube.
We have the dimensional formula for side length as [M0 L1 T0]. Thus, dimensional formula for volume would be found as follows,
Dimensional Formula of Volume = [M0 L1 T0]3 = [M0 L3 T0]
Dimensional Formula of Volume = [M0 L3 T0]
What is 1 cubic metre?
1 cubic metre is the SI unit of volume abbreviated as 1 m3. It represents the volume of a cube having side length equal to 1 metre.
Unit of Volume – SI Unit, CGS Unit
Unit of Volume is cubic meter represented as m3. Volume is a measure of the capacity of any vessel or a three-dimensional body. In the International System of Units (SI), the unit of volume is m3. Volume can also be represented in other units such as cubic centimetres, litres, millilitres, gallons, etc.
In this article, we will learn the definition of volume, its unit in various systems, some solved examples, and frequently asked questions related to the unit of volume.
