BTU/hr to HP: The Definitive Guide

Struggling to understand the relationship between British Thermal Units per hour (BTU/hr) and horsepower (HP)? You're not alone! This comprehensive guide will demystify the conversion process, providing valuable insights and practical applications.

Understanding BTU/hr and HP

BTU/hr is a unit of measurement for heat energy, representing the amount of heat required to raise 1 pound of water by 1 degree Fahrenheit within an hour. HP, on the other hand, is a unit of measurement for mechanical power, representing the power required to lift 33,000 pounds one foot high in one minute.

While these units may seem unrelated, they can be converted to each other using the following formula:

1 HP = 2,544 BTU/hr
