1. What is a kW to BTU/h 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 technicians convert between these common power units used in heating and cooling systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{btu} \) — Heat transfer rate (BTU/h)
• \( P_{kW} \) — Power (kilowatts)

Explanation: The conversion factor 3412 represents the number of BTUs per hour equivalent to one kilowatt of power.

3. Importance of Power Unit Conversion

Details: Accurate conversion between kW and BTU/h is essential for proper equipment sizing, energy calculations, and system comparisons in heating and cooling applications.

4. Using the Calculator

Tips: Simply enter the power value in kilowatts (must be > 0) and the calculator will instantly 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: When would I need this conversion?
A: When comparing equipment specifications (some use kW, others BTU/h) or calculating heating/cooling requirements.

Q3: Is this conversion exact?
A: Yes, the 3412 factor is a defined conversion constant, not an approximation.

Q4: Can I convert BTU/h back to kW?
A: Yes, divide BTU/h by 3412 to get kW. We may add this reverse calculation in future updates.

Q5: Does this work for both heating and cooling?
A: Yes, the conversion applies equally to heating and cooling power measurements.
