1. What is Watts to BTU/hr Conversion?

The conversion between watts and BTU per hour is essential for comparing electrical power to thermal energy output. This is particularly useful for HVAC systems, heaters, and other energy conversion applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Watts \) — Electrical power input in watts
• \( 3.41214 \) — Conversion factor (BTU/hr per watt)

Explanation: One watt of electrical power is equivalent to 3.41214 BTU of thermal energy per hour.

3. Importance of Power Conversion

Details: Accurate power conversion is crucial for system design, energy efficiency calculations, and comparing electrical systems to thermal systems.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why convert watts to BTU/hr?
A: This conversion helps compare electrical power input to thermal output, important for heating systems and energy efficiency calculations.

Q2: Is this conversion exact?
A: The conversion factor 3.41214 is based on the International Table BTU, which is the most commonly used definition.

Q3: Can this be used for air conditioning systems?
A: Yes, this conversion applies to both heating and cooling systems when comparing electrical input to thermal energy transfer.

Q4: What about other power units?
A: For kilowatts, first convert to watts (1 kW = 1000 W) then apply the conversion factor.
