How Many BTU in a Watt?

Converting British Thermal Units (BTUs) to Watts

In the realm of energy measurements, two units often encounter are British Thermal Units (BTUs) and watts (W). Understanding the relationship between these units is crucial for various applications, from HVAC systems to home energy management. This comprehensive guide will delve into the conversion between BTUs and watts, providing valuable insights and practical examples.

Understanding BTUs and Watts

BTUs (British Thermal Units) measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit.

Watts (W) measure the rate of energy transfer or consumption, often used to quantify electrical power. One watt is equivalent to one joule of energy per second.

Conversion Formula: BTU to Watt

The conversion formula from BTUs to watts is:

1 BTU = 0.293071 W

This means that one BTU is equivalent to 0.293071 watts.

Conversion Formula: Watt to BTU

Conversely, the conversion formula from watts to BTUs is:

1 W = 3.412142 BTUs

This means that one watt is equivalent to 3.412142 BTUs.
