1. What is Watts to BTU Conversion?

The Watts to BTU conversion calculates the heat output in British Thermal Units (BTU) per hour from electrical power measured in watts. This is commonly used for sizing air conditioners, heaters, and other HVAC equipment.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Q \) — Heat output in BTU per hour
• \( W \) — Electrical power in watts
• 3.412142 — Conversion factor (1 watt = 3.412142 BTU/hr)

Explanation: The conversion factor comes from the relationship between the watt (a unit of power in the International System of Units) and the British Thermal Unit (a traditional unit of energy).

3. Importance of BTU Conversion

Details: Accurate BTU calculation is essential for properly sizing HVAC equipment, ensuring energy efficiency, and maintaining comfortable indoor environments.

4. Using the Calculator

Tips: Enter the wattage of your electrical device or system. The calculator will instantly show the equivalent heat output in BTU per hour.
