1. What is BTU to Watts Conversion?

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

Purpose: It helps in comparing or converting heating/cooling capacities between systems that use different power units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The conversion factor 0.293 comes from the exact conversion where 1 BTU/h equals approximately 0.29307107 Watts.

3. Importance of Power Unit Conversion

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 0.293?
A: This is because 1 BTU equals approximately 1055.06 Joules, and 1 Watt is 1 Joule per second. The hourly conversion results in the 0.293 factor.

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

Q3: Is this conversion exact?
A: The 0.293 factor is rounded. For precise calculations, use 0.29307107.

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

Q5: Does this apply to all types of BTU?
A: This uses the International Table BTU (IT BTU), the most common standard.
