1. What is a BTU to Watt Conversion Calculator?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to Watts (W), two common units of power measurement.

Purpose: It helps in comparing and converting between different power measurement systems, commonly used in heating, cooling, and electrical applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Power in Watts
• \( BTU \) — Power in British Thermal Units per hour

Explanation: 1 Watt is equal to approximately 3.412 BTU per hour. The conversion is a simple division by this constant factor.

3. Importance of Power Unit Conversion

Details: Accurate conversion between these units is essential when working with equipment specifications that use different measurement systems, especially in HVAC and energy efficiency calculations.

4. Using the Calculator

Tips: Simply enter the BTU/h value you want to convert. The calculator will automatically compute the equivalent Watt value.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.412?
A: This is the exact conversion factor between BTU/h and Watts, based on the International Table BTU definition.

Q2: What's the difference between BTU and Watts?
A: BTU (British Thermal Unit) is a traditional unit of heat energy, while Watt is the SI unit of power. 1 W = 3.412 BTU/h.

Q3: When would I need this conversion?
A: Common uses include sizing air conditioners (rated in BTU) to electrical capacity (rated in Watts), or comparing heating system specifications.

Q4: Is this conversion exact?
A: Yes, when using the International Table BTU definition. Other BTU definitions may have slightly different conversion factors.

Q5: Can I convert Watts to BTU using this?
A: For the reverse calculation, you would multiply Watts by 3.412 to get BTU/h.
