    \[W = \frac{J}{ s }=\frac{ Nm }{ s }\] solving for meter we rearrange the equation as such\[m =\frac{ Ws }{ N }\]

    W is watts, s is seconds, N is newtons

    Oh and \[N = Mg\] Newtons in this equation is equal to the weight which is the force of gravity. This equals mass times the acceleration due to gravity
