BTU/hr to kW: Making Sense of Energy Conversions

In the realm of energy management, navigating the intricate world of unit conversions is essential. Understanding the relationship between British Thermal Units per hour (BTU/hr) and kilowatts (kW) empowers individuals to make informed decisions regarding energy usage and efficiency.

Why Convert BTU/hr to kW?

BTU/hr is commonly used to measure the heating or cooling capacity of appliances, while kW is often employed to determine the power consumption of electrical devices. By converting between these units, you can easily compare the energy efficiency of different systems or estimate their energy requirements.

Formula for Converting BTU/hr to kW

The conversion formula is straightforward:

kW = BTU/hr ÷ 3412

Example Conversion

To convert 10,000 BTU/hr to kW:

kW = 10,000 BTU/hr ÷ 3412
= 2.93 kW
