# What is Dimensional Formula of Hubble constant ?

Posted in Dimensional Formulae | Email This Post |Hubble constant can be defined as the ratio of receding velocity of an extra galactic object to the distance of that object.

Mathematically,

**Hubble constant(H _{o}) = Receding velocity(v)/distance(d) .**

Dimensional Formula of Receding velocity = M^{0}L^{1}T^{-1}

Dimensional Formula of Distance = M^{0}L^{1}T^{0}

Putting these values in the given equation we get,

**Dimensional Formula of Hubble constant = M ^{0}L^{0}T^{-1}**

**SI Unit of Hubble Constant is sec**.
