1. What is BTU to kW Conversion?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to kilowatts (kW), a common power conversion in heating and cooling systems.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of BTU to kW Conversion

Details: Accurate conversion is essential for equipment sizing, energy efficiency calculations, and comparing system specifications that use different units.

4. Using the Calculator

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

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: Can I convert kW back to BTU?
A: Yes, simply multiply kW by 3412 to get BTU/h.

Q3: Is this for BTU/h or just BTU?
A: This converts BTU per hour (BTU/h) to kW, which are both power units. For energy (not power) conversions, the calculation would be different.

Q4: What's a typical BTU rating for air conditioners?
A: Residential AC units typically range from 5,000 BTU/h (1.5 kW) to 36,000 BTU/h (10.5 kW).

Q5: How precise is this conversion?
A: The calculator uses the standard conversion factor with 4 decimal places for maximum accuracy.
