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 in comparing and converting between different power measurement systems commonly used in heating, cooling, and electrical applications.

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 kilowatt is equal to 3412 BTU per hour, so we divide the BTU value by 3412 to get the equivalent in kilowatts.

3. Importance of Power Conversion

Details: Accurate conversion between these units is essential when working with equipment specifications, energy efficiency calculations, and international standards.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The value must be greater than 0.

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: When would I need this conversion?
A: Common when comparing air conditioner capacities (often in BTU) with electrical power requirements (often in kW).

Q3: Is this conversion exact?
A: Yes, for the International Table BTU. Other BTU definitions exist but are rarely used in modern applications.

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

Q5: How precise is the result?
A: The calculator shows 6 decimal places for precision in technical applications.
