BTU/hr to Watt: A Comprehensive Guide to Conversion and Applications

Understanding the conversion between British Thermal Units per hour (BTU/hr) and watts (W) is crucial in various engineering and energy-related fields. This conversion involves the relationship between heat and electrical power, which can be confusing at first. This article aims to provide a comprehensive guide to BTU/hr to watt conversion, exploring the formulas, applications, and practical tips to enhance your understanding.

Understanding the Units

BTU/hr (British Thermal Unit per hour): A unit of energy, specifically the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit in one hour.

Watt (W): A unit of power, representing the rate at which electrical work is done. One watt is equal to one joule of energy expended per second.

Conversion Formula

The conversion formula between BTU/hr and watts is:

1 BTU/hr = 0.293071 W

or

1 W = 3.41214 BTU/hr
