1. What is a BTU to Kilowatts 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:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Q_{btu} \) — Power in British Thermal Units per hour (BTU/h)

Explanation: 1 kW is equivalent to 3412 BTU/h, so we divide the BTU value by 3412 to get the equivalent in kilowatts.

3. Importance of Power Unit Conversion

Details: Accurate conversion between these units is essential for equipment sizing, energy calculations, and comparing system specifications.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The result will be displayed in kilowatts with 6 decimal places for precision.

5. Frequently Asked Questions (FAQ)

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

Q2: When would I need this conversion?
A: Common uses include HVAC system design, generator sizing, and comparing appliance energy ratings.

Q3: How precise is this conversion?
A: The calculator provides results with 6 decimal places, suitable for most engineering applications.

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

Q5: What's a typical BTU rating for home air conditioners?
A: Residential AC units typically range from 5,000 BTU/h (small window unit) to 60,000 BTU/h (whole-house system).
