1. What is BTU/hr to Watts Conversion?

The BTU/hr to Watts conversion is used to translate thermal energy units (British Thermal Units per hour) to electrical power units (Watts). This is particularly useful in HVAC systems, power generation, and energy efficiency calculations.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( W \) — Power in Watts
• \( BTU/hr \) — British Thermal Units per hour
• 3.412142 — Conversion factor (exact value)

Explanation: 1 Watt is equal to approximately 3.412142 BTU per hour. This conversion factor comes from the definition of BTU and Watt units.

3. Practical Applications

Details: This conversion is essential when comparing heating/cooling systems (rated in BTU/hr) with electrical systems (rated in Watts), or when calculating energy efficiency of appliances.

4. Using the Calculator

Tips: Simply enter the BTU/hr value you want to convert. The calculator will automatically compute the equivalent Wattage. Values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.412142?
A: This exact value comes from the definition that 1 BTU = 1055.05585262 Joules and 1 Watt = 1 Joule/second. The factor accounts for hours to seconds conversion.

Q2: Can I convert Watts to BTU/hr with this?
A: Yes, the reverse calculation is BTU/hr = Watts × 3.412142. Just multiply instead of divide.

Q3: Is this conversion affected by temperature?
A: No, the conversion factor is constant regardless of temperature, as it's based on the International Table BTU definition.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact when using the International Table BTU definition.

Q5: When would I need this conversion?
A: Common uses include sizing air conditioners, comparing electric heaters to gas heaters, or calculating energy consumption of appliances.
