1. What is the kW to BTU/hr Conversion?

The kW to BTU/hr conversion calculates the equivalent heating or cooling capacity between kilowatts (a unit of power) and British Thermal Units per hour (a common measurement for heating and cooling systems).

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( kW \) — Power in kilowatts
• \( 3412.142 \) — Conversion factor (exact multiplier)

Explanation: This conversion allows you to translate electrical power (kW) to thermal energy output (BTU/hr), which is particularly useful for HVAC system sizing and energy calculations.

3. Importance of Power Conversion

Details: Accurate conversion between kW and BTU/hr is essential for proper HVAC system design, energy efficiency calculations, and comparing heating/cooling capacities across different measurement systems.

4. Using the Calculator

Tips: Enter the power value in kilowatts (kW). The value must be a positive number. The calculator will automatically compute the equivalent BTU/hr value.

5. Frequently Asked Questions (FAQ)
