1. What is Watt to BTU Conversion?

The watt to BTU conversion calculates the equivalent British Thermal Units per hour from electrical power measured in watts. This conversion is essential for comparing electrical heating systems with thermal systems and for HVAC applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( BTU/h \) — British Thermal Units per hour
• \( W \) — Electrical power in watts
• \( 3.41214 \) — Conversion factor (watts to BTU/h)

Explanation: One watt of electrical power is equivalent to 3.41214 BTU per hour of thermal energy, based on the standard conversion factor.

3. Importance of Power Conversion

Details: Accurate power conversion is crucial for HVAC system design, electrical heating equipment selection, energy efficiency calculations, and comparing different types of heating systems.

4. Using the Calculator

Tips: Enter the power value in watts. The value must be positive and valid. The calculator will automatically compute the equivalent BTU per hour.
