BTU Calculator

The BTU calculator converts the electrical load of your equipment into the cooling units used by HVAC engineers: BTU per hour and tons of refrigeration.

Every watt your equipment consumes becomes heat that the cooling system must remove. Enter the total power draw of the room or rack and the calculator returns the BTU/hr output and the tons of cooling required, so you can compare against the capacity of your AC units.
