Abstract
In the present chapter, a glimpse has been given about futuristic view on definitions of base units of the international system of units SI. Methods of defining base units in terms of physical constants of one element namely hydrogen one standard namely frequency indestructible and invariable physical constants some invariant physical phenomenon like Einstein matter energy relation have been discussed. The latest thinking about redefinitions of kilogram, ampere, kelvin and mole have also been discussed
