1. What is the BTU to kW Conversion?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to kilowatts (kW), a common power conversion in heating and cooling systems.

Purpose: It helps HVAC professionals, engineers, and technicians convert between these two common power measurement units.

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 equals 3412 BTU/h, so dividing BTU/h by 3412 converts to kW.

3. Importance of BTU to kW Conversion

Details: This conversion is essential when working with equipment specifications that use different measurement systems or when comparing system efficiencies.

4. Using the Calculator

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

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 definition.

Q2: Can I use this for cooling capacity?
A: Yes, this works for both heating and cooling capacity conversions.

Q3: How accurate is this conversion?
A: It's mathematically exact for the International Table BTU. Other BTU definitions may vary slightly.

Q4: What's a typical BTU/h value for home AC?
A: Residential air conditioners typically range from 5,000 BTU/h (1.5 kW) to 36,000 BTU/h (10.5 kW).

Q5: How do I convert back from kW to BTU/h?
A: Multiply kW by 3412 to get BTU/h.
