BTU hr to KW: A Comprehensive Conversion Guide for Thermal Energy

Introduction

The conversion between BTU hr (British Thermal Unit per hour) and kW (kilowatt) is crucial in various fields, including heating, ventilation, air conditioning (HVAC), and energy management. This comprehensive guide will provide you with the necessary knowledge and practical tools to perform this conversion accurately.

Understanding BTU and kW

BTU hr: Represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit in one hour.
kW: Measures electrical power and represents the rate at which energy is consumed or generated, equivalent to 1,000 watts.

Conversion Formula

The conversion formula between BTU hr and kW is:

1 BTU hr = 0.293071 kW

1 kW = 3.412142 BTU hr

How to Convert BTU hr to kW

To convert BTU hr to kW, simply multiply the BTU hr value by 0.293071.
