1. What is a BTU to kW Conversion Calculator?

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 equals 3412 BTU/h, so dividing BTU/h by this conversion factor gives the equivalent in kW.

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: Enter the BTU/h value (must be > 0). The result will show the equivalent power in kilowatts with 6 decimal places for precision.

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 BTU/h equals 1 kW?
A: This is the standard conversion factor based on the International Table BTU definition (1 BTU = 1055.056 Joules).

Q2: When would I need this conversion?
A: When working with HVAC equipment specifications, energy consumption calculations, or comparing international system ratings.

Q3: How precise is this conversion?
A: The calculator provides 6 decimal places, though most practical applications only need 2-3 decimal places.

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

Q5: Does this work for both heating and cooling capacities?
A: Yes, the conversion is the same whether measuring heating or cooling capacity.
