1. What is a BTU/h to kW Calculator?

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

Purpose: It helps HVAC professionals, engineers, and technicians convert between these common power measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power in kilowatts (kW)
• \( Q_{btu} \) — Power in British Thermal Units per hour (BTU/h)

Explanation: 1 kW is equal to 3412 BTU/h, so we divide the BTU/h value by 3412 to get the equivalent in kW.

3. Importance of Power Unit Conversion

Details: Accurate conversion between these units is essential for equipment sizing, energy calculations, and system design in heating and cooling applications.

4. Using the Calculator

Tips: Simply enter the BTU/h value (must be > 0) and the calculator will instantly provide the equivalent kW value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3412?
A: This is the exact conversion factor where 1 kW = 3412.142 BTU/h, based on the International Table BTU definition.

Q2: When would I need to convert BTU/h to kW?
A: Common when working with heating/cooling equipment specifications, energy audits, or comparing systems using different measurement units.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact. Any rounding would occur only in the displayed result.

Q4: Can I convert kW back to BTU/h?
A: Yes, simply multiply kW by 3412 to get BTU/h. We may add a reverse calculator in future updates.

Q5: What's a typical BTU/h rating for residential air conditioners?
A: Common sizes range from 5,000 BTU/h (small window unit) to 60,000 BTU/h (whole-house systems).
