1. What is a BTU/hr to Watts Calculator?

Definition: This calculator converts power measurements from British Thermal Units per hour (BTU/hr) to Watts (W).

Purpose: It helps in comparing and converting heating/cooling capacities between different measurement systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: 1 Watt equals approximately 3.412 BTU/hr, so we divide BTU/hr by this conversion factor.

3. Importance of Power Unit Conversion

Details: Converting between BTU/hr and Watts is essential when working with equipment specifications from different regions or comparing heating/cooling systems.

4. Using the Calculator

Tips: Simply enter the BTU/hr value (must be > 0) and the calculator will provide the equivalent in Watts.

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/hr based on the international table BTU definition.

Q2: When would I need this conversion?
A: When comparing air conditioner capacities (often in BTU/hr) with electrical specifications (in Watts).

Q3: Is this conversion exact?
A: Yes, for the international table BTU definition (1 BTU = 1055.056 Joules).

Q4: Can I convert Watts to BTU/hr?
A: Yes, simply multiply Watts by 3.412 to get BTU/hr.

Q5: What's a typical BTU/hr rating for home air conditioners?
A: Residential AC units typically range from 5,000 BTU/hr (small window unit) to 36,000 BTU/hr (whole-house system).
