Watt
Unit of measurement for power, used by the international system. Watts are used to measure the power of appliances and calculate energy consumption. The most interesting value is the watt hour i.e. the consumption of an appliance per hour of use (the most frequently used is the kilowatt hour equal to 1000 Watts/h).
BTU (British Thermal Unit)
This is a unit of measurement for energy, adopted in the United Stated and United Kingdom, and currently used instead of Watts (W). A BTU is defined by the quantity of heat required to raise the temperature of 454 grams of water from 60 to 61 degrees Fahrenheit. BTUs/h are normally used in the definition of the cooling power of air conditioning systems as well as of the heating power of fuel.
For W to BTU/h conversions, 1 W is equal to 3.41 BTU/h. Therefore to convert BTU/h into Watts you need to divide by 3.41; to convert Watts into BTU/h you need to multiply by 3.41.
