1. What is kW to BTU/h Conversion?

Definition: This calculator converts cooling capacity 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 measurement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Cooling capacity in BTU/h
• \( P \) — Cooling capacity in kilowatts (kW)

Explanation: 1 kW of cooling capacity is equivalent to 3,412 BTU/h.

3. Importance of the Conversion

Details: Many air conditioning systems specify capacity in both kW and BTU/h. This conversion is essential for system sizing and comparison.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why 3,412 specifically?
A: This is the exact conversion factor between kW and BTU/h based on their definitions in the International System of Units.

Q2: Is this conversion only for cooling?
A: No, the same conversion applies to heating capacity as well.

Q3: How precise is this conversion?
A: The conversion factor 3,412 is exact, though equipment ratings may be rounded.

Q4: What's a typical kW to BTU/h conversion for home AC units?
A: A 3.5 kW unit would be about 12,000 BTU/h (commonly called a "1-ton" unit).

Q5: Do I need to consider efficiency in this conversion?
A: No, this converts power units only. Efficiency would affect actual cooling output.
