1. What is a kW to BTU Conversion Calculator?

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

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:

• \( Q_{btu} \) — Heat output in BTU per hour
• \( P_{kW} \) — Power in kilowatts

Explanation: 1 kW equals 3412 BTU/h exactly by definition of these units.

3. Importance of Power Unit Conversion

Details: Many heating and cooling systems specify capacity in BTU/h, while electrical systems often use kW. Conversion between these units is essential for system design and comparison.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts (must be > 0) and the calculator will instantly show the equivalent BTU/h value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This exact value comes from the definition of BTU in terms of kilowatt-hours (1 kWh = 3412 BTU).

Q2: Is this conversion valid for both heating and cooling?
A: Yes, the conversion works for any power measurement, whether heating or cooling capacity.

Q3: How precise is this conversion?
A: The 3412 factor is exact, not an approximation, so results are mathematically precise.

Q4: What's a typical kW to BTU/h conversion for air conditioners?
A: A 3 kW AC unit would be about 10,236 BTU/h (3 × 3412).

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