1. What is a kW to BTU Conversion Calculator?

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

Purpose: It helps HVAC professionals, engineers, and energy specialists convert between these common power units.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q_{btu} = P_{kW} \times 3412 \]

Where:

\( Q_{btu} \) — Heat output in BTU per hour
\( P_{kW} \) — Power in kilowatts

Explanation: 1 kW is equal to 3412 BTU/h, as 1 BTU/h equals 0.00029307107 kW.

3. Importance of kW to BTU Conversion

Details: This conversion is essential when comparing heating/cooling systems or when working with equipment that uses different power measurement standards.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts (kW) and the calculator will automatically compute the equivalent BTU/h.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I convert BTU/h back to kW?
A: Yes, divide BTU/h by 3412 to get kW. Our calculator performs one-way conversion only.

Q3: Is this for cooling or heating BTUs?
A: The conversion is the same for both heating and cooling applications.

Q4: What's a typical kW to BTU conversion for air conditioners?
A: A 3.5 kW AC unit would be approximately 12,000 BTU/h (3.5 × 3412 ≈ 12,000 BTU/h).

Q5: Does this account for efficiency or COP?
A: No, this is a direct unit conversion. For actual performance, you would need to factor in system efficiency.
