BTU/h to Watts: A Comprehensive Conversion Guide

Understanding the BTU/h and Watt Units

British thermal units per hour (BTU/h) and watts (W) are both units of power used to measure the rate at which energy is transferred. BTU/h is commonly used in the United States for heating and cooling applications, while watts are used globally for various electrical and mechanical purposes.

Conversion Formula and Relationship

The conversion formula between BTU/h and watts is:

1 BTU/h = 0.2931 W
1 W = 3.412 BTU/h

This formula indicates that 1 BTU/h is approximately equal to 0.2931 watts, and 1 watt is approximately equal to 3.412 BTU/h.
