1. What is a kW to BTU 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:

Where:

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

Explanation: 1 kW is equal to 3412 BTU/h, as defined by the International System of Units.

3. Importance of Power Conversion

Details: Accurate conversion between kW and BTU/h is essential for equipment sizing, energy calculations, and system comparisons.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 specifically?
A: This is the exact conversion factor where 1 kW = 3412.142 BTU/h, based on the International Table BTU.

Q2: Is this for electrical or thermal kW?
A: The conversion works for both, as it's a direct unit conversion regardless of energy type.

Q3: How precise is this conversion?
A: The 3412 factor provides precision to 4 significant figures, sufficient for most practical applications.

Q4: Can I convert BTU/h back to kW?
A: Yes, simply divide BTU/h by 3412 to get kW.

Q5: Where is this conversion commonly used?
A: Primarily in HVAC systems, power generation, and energy efficiency calculations.
