1. What is a Heat Output Calculator (kW from BTU)?

Definition: This calculator converts heat output from British Thermal Units (BTU) to kilowatts (kW).

Purpose: It helps HVAC professionals, engineers, and energy specialists convert between these common heat measurement units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( kW \) — Heat output in kilowatts
• \( BTU \) — Heat output in British Thermal Units per hour

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

3. Importance of Heat Output Conversion

Details: Accurate conversion between BTU and kW is essential for equipment sizing, energy efficiency calculations, and comparing heating systems.

4. Using the Calculator

Tips: Enter the BTU value (must be > 0) and the calculator will automatically compute the equivalent kW value.

5. Frequently Asked Questions (FAQ)

Q1: Why 3412 as the conversion factor?
A: 1 kW equals 3412.142 BTU/h exactly, as defined by the International System of Units.

Q2: When would I need this conversion?
A: When comparing heating systems, calculating energy usage, or working with equipment that uses different measurement units.

Q3: Is this conversion rate constant?
A: Yes, the conversion factor is always 3412.142 BTU/h per kW, regardless of temperature or other conditions.

Q4: Can I convert kW back to BTU?
A: Yes, multiply kW by 3412 to get BTU/h.

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