1. What is BTU to kW Conversion?

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

Purpose: It helps in comparing or converting heating/cooling capacities between systems that use different measurement units.

2. How Does the Conversion Work?

The calculator uses the formula:

Where:

• \( P \) — Power in kilowatts (kW)
• \( Q \) — Power in British Thermal Units per hour (BTU/h)
• 3412 — Conversion factor (1 kW = 3412.142 BTU/h)

Explanation: The BTU/h value is divided by 3412 to get the equivalent power in kilowatts.

3. Importance of Power Unit Conversion

Details: Converting between BTU/h and kW is essential when working with HVAC systems, electrical equipment specifications, or international projects where different measurement systems are used.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 as the conversion factor?
A: 1 kW is equal to exactly 3412.142 BTU/h, based on the International Table BTU definition.

Q2: How precise is this conversion?
A: The conversion is mathematically exact, though practical applications may round results for convenience.

Q3: Can I convert kW back to BTU/h?
A: Yes, multiply kW by 3412 to get BTU/h (inverse of this calculator's operation).

Q4: Where is this conversion commonly used?
A: Primarily in HVAC (heating, ventilation, air conditioning) and power generation industries.

Q5: What's a typical BTU/h value for home air conditioners?
A: Residential AC units typically range from 5,000 BTU/h (1.5 kW) to 36,000 BTU/h (10.5 kW).
