1 J = 1 kg x m^-2 / s^-2 and, E = P x t 1 J = 1 W x 1 s so, 1 kg x m^-2 / s^-2 = 1 kg x m^-2 / s^-3 x s ?? and now i don't have any idea where I am going with this.

Homework Statement trying to show that the units W m-2 are equivalent to kg s-3 Homework Equations 1 W = 1 J s-1 ? The Attempt at a Solution energy per unit time? p.s. I am very new to physics, a beginner in understanding the whole concept of units, any advice?
