Is this correct - Rs.1 is equal to 1 paisa yesterday got a SMS, and can any one explain it.... One Re= 100ps =10ps x10ps (Notice the how the equation goes haywire from here) =0.1Re X0.1Re =0.01Re = 1 paisa confused... can any one explain it...

Dimensionally, $$100ps\
e10ps\times10ps=100(ps)^2\\\0.01Re\
e0.1Re\times0.1Re=0.01(Re)^2$$

So,

$$1 Re= 100ps =10 \times10\; ps =10 \times0.1\;Re =1 Re\\\ \boxed{1Re = 100 ps}$$
