The $\mathrm{S}.\mathrm{I}$ unit  of pole strength is

Speed of light $c$, acceleration due to gravity $\left(g\right)$ and pressure $\left(p\right)$ are taken as fundamental units, the dimensions of the gravitational constant $G$ are:

The time dependence of a physical quantity is given by $p=p_0{e}^{-\alpha t^2}$ where $\alpha$ is a constant and $t$ is time. The constant $\alpha$
