Your answer is correct for representing energy as indicated by BTU. Air conditioners, however, are rated for their power to cool and usually have capacities indicated in BTU/hr or "tonnes of refrigeration". The SI unit would be watt.

Could someone please tell me what the S I unit is for measureing the output of airconditioners?  In imperial it's B T U. What is the conversion factor to convert B T U's to S I?  Thanks for all your help.
