BTU to WH: Understanding the Energy Conversion

Introduction

British thermal units (BTUs) and watt-hours (WHs) are two units of energy commonly used in different applications and industries. Converting between these units is crucial for various calculations, energy efficiency assessments, and engineering design. This article delves into the conversion process, providing a comprehensive understanding of the relationship between BTUs and WHs.

Definition and Units

British Thermal Unit (BTU): A BTU is defined as the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit at sea level.

Watt-Hour (WH): A WH is defined as the amount of energy delivered by one watt of power for one hour.

Conversion Formula

The conversion formula between BTUs and WHs is:

1 BTU = 0.2931 WH
1 WH = 3.412 BTU
