Dimensional Formula of Energy. The dimensional formula of energy is given by, M 1 L 2 T-2. Where, M = Mass; L = Length; T = Time
Volumetric mass density has dimension M/L 3 or ML –3, or mass over length cubed. In general, the dimension of any physical quantity can be written as \[L^{a}M^{b}T^{c}I^{d}\Theta^{e}N^{f}J^{g}\] for some powers a, b, c, d, e, f, and g. We can write the dimensions of a length in this form with a = 1 and the remaining six powers all set equal ...
We can derive the dimension of energy =\ [ML^ {2}T^ {-2}\] Using Einstein’s famous equation of mass-energy equivalence, which gives the relation between mass and energy conversion and states that. \ [E = mc^ {2} \] Where m= mass and c=velocity. Since mass is measured is kg. Thus the dimension of mass is M.
Find the dimensions of a mathematical expression involving physical quantities. Determine whether an equation involving physical quantities is dimensionally consistent. The dimension of any physical quantity expresses its dependence on the base quantities as a product of symbols (or powers of symbols) representing the base quantities.

By using dimensional formulae, we can see how fundamental quantities are raised to different powers to build a new physical quantity. The powers of fundamental physical quantities are referred to as dimensions. Scientists define energy as the ability to do tasks.
Example: The total energy (E) of a system is composed of internal energy (U), kinetic energy (KE), and potential energy (PE), i.e., EU KE PE . Let’s look at the primary dimensions of each term in this equation:
Thus E, pc and mc2 have dimensions of energy, or GeV. Choosing. units where c = 1, the energy relationship can be written in the simpler form E2 = p2 + m2, with all quantities measured in GeV. Note that in published papers momenta and masses are always expressed as GeV/c and GeV/c2, respectively.
