Kilowatts to Btu/Hr: A Comprehensive Guide to Unit Conversion

Introduction

In the realm of energy conversion, it is often necessary to convert units between kilowatts (kW) and British thermal units per hour (Btu/hr). These two units represent the rate at which energy is transferred or consumed. Understanding the relationship between them is crucial for various applications, from sizing HVAC systems to calculating energy consumption.

Understanding the Units

• Kilowatt (kW): A unit of electrical power representing the rate at which electrical energy is transferred or consumed. One kilowatt is equal to 1,000 watts or 3,412 Btu/hr.
• British thermal unit per hour (Btu/hr): A unit of heat energy representing the rate at which heat is transferred or consumed. One Btu/hr is equal to the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit in one hour.

Conversion Formula

To convert kilowatts to Btu/hr, use the following formula:

Btu/hr = kW x 3,412

To convert Btu/hr to kilowatts, use the following formula:

kW = Btu/hr / 3,412
