Whether you’re sizing a new air conditioner or understanding the specifications of your existing unit, knowing how to convert BTU/hr to kW is crucial. This article provides a comprehensive guide to help you make this conversion effortlessly.

Understanding BTU/hr and kW
BTU/hr (British Thermal Units per hour): Measures the cooling capacity of an air conditioner, indicating how much heat it can remove from a room in one hour.
kW (kilowatt): Measures electrical power, representing the rate at which electricity is consumed.
Conversion Formula
The formula for converting BTU/hr to kW is:
kW = BTU/hr ÷ 3,412
Step-by-Step Conversion
Example: Convert 12,000 BTU/hr to kW
kW = 12,000 ÷ 3,412
kW = 3.52 kW
Conversion Table
For quick reference, here’s a table showing BTU/hr and their corresponding kW values:
BTU/hr | kW |
---|---|
6,000 | 1.76 |
9,000 | 2.63 |
12,000 | 3.52 |
15,000 | 4.41 |
18,000 | 5.29 |
Applications of Conversion
- Sizing air conditioners: Determine the appropriate cooling capacity for your room based on its size, insulation, and heat sources.
- Calculating electricity consumption: Estimate the amount of electricity your air conditioner will consume by converting its BTU/hr rating to kW.
- Comparing air conditioners: Evaluate the efficiency of different units by comparing their BTU/hr to kW ratios.
