1. What is kW to BTU Conversion?

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

Purpose: It helps HVAC professionals and engineers convert between these common units of cooling capacity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Cooling power in BTU/h
• \( P \) — Cooling power in kilowatts (kW)
• 3412 — Conversion factor (1 kW = 3412 BTU/h)

Explanation: The conversion factor comes from the relationship between the two units of power measurement.

3. Importance of Power Unit Conversion

Details: Proper conversion ensures accurate equipment sizing, energy calculations, and specification comparisons in HVAC systems.

4. Using the Calculator

Tips: Simply enter the cooling power in kilowatts (kW) and the calculator will provide the equivalent in BTU/h.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: 1 kW equals 3412.142 BTU/h because 1 watt = 3.412142 BTU/h, and 1 kW = 1000 watts.

Q2: Is this conversion only for cooling power?
A: While commonly used for cooling, the same conversion applies to any power measurement.

Q3: How precise is this conversion?
A: The conversion factor is precise to several decimal places, though practical applications often round to 3412.

Q4: What's a typical kW to BTU conversion for air conditioners?
A: A 1.5 kW AC unit would be about 5,118 BTU/h (1.5 × 3412).

Q5: Can I convert back from BTU to kW?
A: Yes, divide BTU/h by 3412 to get kW (P = Q / 3412).
