BTU/hr to kJ/hr Conversion: Understanding Energy Measurement

Introduction

Energy is a vital aspect of our daily lives, powering everything from our homes to our industries. To ensure efficient energy management, it's crucial to accurately measure and convert between different energy units. This article provides a comprehensive guide to converting British Thermal Units per hour (BTU/hr) to Kilojoules per hour (kJ/hr).

Definition of BTU/hr and kJ/hr

BTU/hr: The British Thermal Unit (BTU) is a unit of energy commonly used in the United States. One BTU is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. BTU/hr represents the rate of heat flow or energy consumption per hour.

kJ/hr: The Kilojoule (kJ) is a unit of energy used in the metric system. It is defined as the energy used to exert a force of one newton over a distance of one meter. kJ/hr signifies the energy consumption rate in kilojoules per hour.

Conversion Formula

The conversion formula for BTU/hr to kJ/hr is:

1 BTU/hr = 0.293071 kJ/hr
