1. What is a BTU to Watts Converter?

Definition: This calculator converts British Thermal Units per hour (BTU/h) to Watts (W), the standard unit of power in the International System of Units.

Purpose: It helps in comparing heating/cooling capacities between systems using different measurement units.

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 equals approximately 3.412 BTU/h, so dividing BTU by this factor converts to Watts.

3. Importance of BTU to Watts Conversion

Details: Essential for HVAC system comparisons, electrical load calculations, and international equipment specifications.

4. Using the Calculator

Tips: Simply enter the BTU/h value to get the equivalent in Watts. Value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 3.412 as the conversion factor?
A: This is the exact conversion factor where 1 Watt = 3.412141633 BTU/h based on the International Table BTU.

Q2: Is this for BTU/h or just BTU?
A: This converts BTU per hour (BTU/h) to Watts, as both are power units (energy per time).

Q3: How accurate is this conversion?
A: The conversion is mathematically exact, though real-world equipment may have efficiency factors to consider.

Q4: When would I need this conversion?
A: When comparing air conditioner BTU ratings to electrical wattage requirements, or converting heater specifications.

Q5: What's a typical conversion example?
A: A 10,000 BTU/h air conditioner requires about 2,930 Watts (10,000 ÷ 3.412).
