1. What is kW to BTU/h Conversion?

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

Purpose: It helps HVAC professionals, engineers, and homeowners compare heating capacities between systems using different measurement units.

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 equivalent to 3412 BTU/h, as 1 BTU = 0.00029307107 kW.

3. Importance of Heat Unit Conversion

Details: Many heating systems in North America use BTU ratings while electrical systems use kW. Conversion allows for accurate comparison and sizing.

4. Using the Calculator

Tips: Simply enter the power in kilowatts (kW) to get the equivalent heat output in BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 specifically?
A: This is the exact conversion factor based on the definition of 1 BTU = the energy needed to raise 1 pound of water by 1°F.

Q2: Is this for both heating and cooling?
A: Yes, the conversion works for both heating and cooling capacities.

Q3: How accurate is this conversion?
A: It's mathematically exact, though real-world system efficiencies may vary.

Q4: What's a typical kW to BTU conversion for home systems?
A: A 5 kW heater = 17,060 BTU/h. Most home systems range from 10,000-100,000 BTU/h.

Q5: Does this account for system efficiency?
A: No, this is a direct unit conversion. Actual output depends on system efficiency.
