1. What is BTU/hr?

BTU/hr (British Thermal Units per hour) is a unit of power that measures energy transfer rate. One BTU represents the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit.

2. Conversion Formula

The conversion formula from kilowatts to BTU/hr is:

Where:

• 1 kW = 1000 watts
• 1 watt = 3.412142 BTU/hr

Explanation: Since 1 kilowatt equals 1000 watts, and each watt equals approximately 3.412142 BTU/hr, we multiply the kilowatt value by both conversion factors.

3. Practical Applications

Details: This conversion is commonly used in heating, ventilation, and air conditioning (HVAC) systems, power plant operations, and energy efficiency calculations where both electrical power (kW) and thermal output (BTU/hr) need to be compared.

4. Using the Calculator

Tips: Simply enter the value in kilowatts (kW) and click "Convert" to get the equivalent value in BTU per hour. The calculator accepts decimal values for precise conversions.
