Calculating Heat Dissipation

To calculate the heat generated by a server so that you can estimate the heat your
cooling system must dissipate, convert the figure for the system's power
requirement from watts to BTU/hr. A general formula for doing this is to multiply
the power requirement figure in watts by 3.412.
