I wonder just how much power it takes to cool 450,000 servers.
450,000 servers * 100 Watts/Server = 45,000,000 watts / 3.413
watts/BTU =
13.1 Million BTU / 12000 BTU/Ton = 1100 Tons of cooling
Error: you MULTIPLY 3.413 to go from watts to BTU, not divide. It's be more like 154,000,000 BTU, /12000 or 12,798 tons.
Well, the bigger problem here is that a watt is a measure of power (engergy/time) and a BTU is a unit of energy. There is no dimensionless conversion factor between the two. -- Crist J.
