Enter the value in Watts into the calculator to determine the equivalent value in BTU; this calculator can also evaluate the value in Watts given the BTU is known.

Watts To Btu Formula

The following formula is used to calculate the conversion from Watts to BTU (British Thermal Units):

BTU = Watts * 3.412142

Variables:

  • BTU is the equivalent value in British Thermal Units
  • Watts is the value in Watts that needs to be converted

To convert from Watts to BTU, simply multiply the value in Watts by 3.412142. This conversion factor accounts for the difference in energy units between the two systems.

What is a Watts To Btu?

Watts to BTU (British Thermal Units) is a conversion factor used in the field of energy measurement. A watt is a unit of power in the International System of Units (SI) and it measures the rate of energy conversion or transfer. On the other hand, a British Thermal Unit (BTU) is a traditional unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. The conversion factor is used to convert the power output of devices from watts to BTUs per hour. The standard conversion factor is that 1 watt is equivalent to approximately 3.412142 BTUs per hour. This conversion is commonly used in various fields such as heating and cooling systems, power plants, and appliances.
