1. What is a BTU to kW Calculator?

Definition: This calculator converts power measurements from British Thermal Units per hour (BTU/h) to kilowatts (kW).

Purpose: It helps HVAC professionals, engineers, and technicians convert between these common power units for heating and cooling systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Power in kilowatts (kW)
• \( Q \) — Power in British Thermal Units per hour (BTU/h)

Explanation: 1 kW is equal to 3412 BTU/h, so we divide the BTU/h value by 3412 to get the equivalent in kW.

3. Importance of BTU to kW Conversion

Details: Many heating and cooling systems are rated in BTU/h, while electrical systems are often rated in kW. This conversion helps in system design and comparison.

4. Using the Calculator

Tips: Simply enter the BTU/h value (must be > 0) and the calculator will provide the equivalent power in kW.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor between BTU/h and kW, based on the international definition of these units.

Q2: How accurate is this conversion?
A: The conversion is mathematically exact, though practical measurements may have instrument-related uncertainties.

Q3: Can I convert kW back to BTU/h?
A: Yes, simply multiply kW by 3412 to get BTU/h.

Q4: Is this for both heating and cooling systems?
A: Yes, the conversion applies equally to both heating and cooling power measurements.

Q5: Why show 6 decimal places?
A: For precision in engineering calculations, though you may round as needed for your application.
