1. What is a BTU/h to kW Calculator?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kW \) — Power in kilowatts
• \( BTU/h \) — Power in British Thermal Units per hour

Explanation: The conversion factor 0.000293 comes from the exact relationship where 1 BTU/h equals approximately 0.00029307107 kW.

3. Importance of Power Unit Conversion

Details: Accurate conversion between these units is essential for equipment specification, energy calculations, and international standards compliance.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The result will be displayed in kilowatts (kW).

5. Frequently Asked Questions (FAQ)

Q1: Why convert BTU/h to kW?
A: kW is the standard SI unit for power, while BTU/h is commonly used in heating/cooling systems. Conversion is needed for standardization.

Q2: How precise is this conversion?
A: The calculator uses a 6-decimal precision for accurate results in most engineering applications.

Q3: What's a typical BTU/h rating for air conditioners?
A: Residential AC units typically range from 5,000 BTU/h to 36,000 BTU/h (about 1.5 kW to 10.5 kW).

Q4: Can I convert kW back to BTU/h?
A: Yes, use the inverse formula: BTU/h = kW × 3412.142.

Q5: Why is the result so small?
A: 1 kW equals about 3412 BTU/h, so BTU/h values convert to much smaller kW numbers.
