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 using different measurement units.

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: The conversion factor 3412 represents the number of BTU/h in one kilowatt (1 kW = 3412.142 BTU/h).

3. Importance of BTU to kW Conversion

Details: Many heating and cooling systems specify capacity in BTU/h, while electrical systems often use kW. Conversion helps in system comparison and sizing.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The result will show the equivalent power in kilowatts.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: 1 kW equals exactly 3412.142 BTU/h, based on the international BTU definition (1 BTU = 1055.05585262 joules).

Q2: How accurate is this conversion?
A: The conversion is mathematically exact when using the international BTU definition.

Q3: Can I convert kW back to BTU/h?
A: Yes, multiply kW by 3412 to get BTU/h.

Q4: What's a typical BTU/h rating for air conditioners?
A: Residential AC units typically range from 5,000 BTU/h (small window unit) to 60,000 BTU/h (whole-house system).

Q5: Why do we use BTU/h instead of just BTU?
A: BTU/h indicates power (energy per time), while BTU alone is just energy. Power units are needed for capacity ratings.
