1. What is BTU/hr to kW Conversion?

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

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:

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

Explanation: 1 kW is equivalent to 3412 BTU/h, so dividing BTU/h by 3412 converts to kW.

3. Importance of Power Unit Conversion

Details: Accurate conversion between units is essential for equipment specification, energy calculations, and system design.

4. Using the Calculator

Tips: Enter the BTU per hour value (must be > 0) and click Calculate to get the equivalent in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This comes from the definition of BTU and kW - 1 kW = 3412.142 BTU/h exactly.

Q2: When would I need this conversion?
A: When working with HVAC systems, power generation, or any equipment that uses different power units.

Q3: How precise is this conversion?
A: The calculator shows 6 decimal places for precision, though practical applications may need fewer.

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

Q5: What's a typical BTU/h rating for air conditioners?
A: Residential AC units typically range from 5,000 to 60,000 BTU/h (1.5 to 17.6 kW).
