Dimensional Analysis in General Theory of Relativity

Use of natural unit is utmost important for research in high energy physics, particularly in the fields of ‘Elementary Particle Physics’, ‘Astro-particle Physics’ and `Physical Cosmology', because all the parameters turn out to be dimensionless. However, it is suggestive to work in a system of units, in which all the kinematical parameters may be expressed in terms of different powers of the Planck's mass or equivalently the energy. Here we explicitly exhibit the use of the natural units, some associated problems and also the proposed system of units in connection with their application in ‘General Theory of Relativity
