Use this calculator to convert BTU to Watts (W).
If, instead, you need to convert Watts to BTU per hour use the Watts to BTU/hr Converter.
Watt:
What are Watts?
Watts are the unit of measurement for power used in the International System of Units. Watts are used to measure the power of appliances and calculate energy consumption.
The most used multiples and submultiples of Watts are:
- milliwatt (mW) = 0.001 W
- kilowatt (kW) = 1000 W
- megawatt (MW) = 1 000 000 W
- gigawatt (GW) = 1 000 000 000 W
- terawatt (TW) = 1 000 000 000 000 W
In everyday life we often hear about Watts in terms of Watt-hours. Watt-hours are the total energy (not power!) supplied when a power of one watt (W) is maintained for one hour (h).
What is BTU (British Thermal Unit)
This is a unit of measurement for energy, adopted in the United States and the United Kingdom and currently used instead of Watts (W).
A BTU is defined as the amount of heat required to raise the temperature of 1 pound of water from 60 to 61 degrees Fahrenheit. BTU/hr is commonly used in defining the cooling power of air conditioning systems and the heating power of fuel.
How to use our BTU/h -> Watt converter
Type a value in the Watts field to convert the value to BTU/h.
Alternative to the calculator
To make the conversion, just remember that
- 1 W is equal to 3.41 BTU/h. Therefore, to convert BTU/h to Watts you need to divide by 3.41 (i.e. multiply by 0.29307107);
- To convert Watts to BTU/h you need to multiply by 3.41.
