1. What is kW to BTU Conversion?

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

Purpose: It helps in comparing and converting between different power measurement units used in heating, cooling, and energy systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Heat output (BTU/h)
• \( P \) — Power input (kW)

Explanation: 1 kW is equal to 3412 BTU/h, as defined by the International System of Units.

3. Importance of Power Conversion

Details: Accurate conversion between kW and BTU/h is essential for sizing HVAC equipment, comparing energy efficiency, and international engineering projects.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts. The result will show the equivalent in BTU per hour.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor defined by the International System of Units (1 kW = 3412.142 BTU/h).

Q2: Is this for both heating and cooling?
A: Yes, the conversion applies equally to heating and cooling power measurements.

Q3: What's the difference between BTU and BTU/h?
A: BTU measures energy, while BTU/h measures power (energy per time).

Q4: How accurate is this conversion?
A: It's mathematically exact, though real-world equipment efficiency may vary.

Q5: Can I convert BTU/h back to kW?
A: Yes, divide BTU/h by 3412 to get kW.
