1. What is Watts to BTU/hr Conversion?

The conversion between watts and BTU/hr (British Thermal Units per hour) is essential for comparing power measurements between the metric system (watts) and the imperial system (BTU/hr). This conversion is commonly used in heating, cooling, and energy applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Watts \) — Power in watts (W)
• \( 3.41214 \) — Conversion factor from watts to BTU/hr

Explanation: One watt is equal to approximately 3.41214 BTU per hour. This conversion factor is derived from the definition of the BTU.

3. Importance of Power Conversion

Details: Accurate power conversion is crucial for comparing heating/cooling capacities, sizing equipment, and energy calculations across different measurement systems.

4. Using the Calculator

Tips: Enter power in watts (must be a positive number). The calculator will instantly provide the equivalent in BTU/hr.

5. Frequently Asked Questions (FAQ)

Q1: Why convert watts to BTU/hr?
