1. What is Watt to BTU/hr Conversion?

The conversion between watts and BTU/hr (British Thermal Units per hour) is essential in comparing power measurements between the metric system (watts) and the imperial system (BTU/hr). This is particularly useful in heating, ventilation, and air conditioning (HVAC) applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

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

Explanation: One watt is equal to 3.412142 BTU per hour. This conversion factor is derived from the definition of BTU and the relationship between different units of power.

3. Practical Applications

Details: This conversion is commonly used in HVAC systems, electrical heating equipment specifications, and energy efficiency calculations where both metric and imperial units are used.

4. Using the Calculator

Tips: Simply enter the power value in watts and click calculate. The result will show the equivalent power in BTU per hour.

5. Frequently Asked Questions (FAQ)

Q1: Why convert watts to BTU/hr?
A: Many heating systems in the US use BTU/hr ratings, while electrical systems use watts. Conversion allows comparison between different systems.

Q2: How accurate is this conversion?
A: The conversion factor is exact, so the calculation is mathematically precise.

Q3: What's the difference between BTU and BTU/hr?
A: BTU measures energy, while BTU/hr measures power (energy per unit time).

Q4: Can I convert BTU/hr back to watts?
A: Yes, divide BTU/hr by 3.412142 to get watts.

Q5: Where is this conversion most commonly used?
A: Primarily in HVAC systems, especially when comparing electric heaters (watts) with gas heaters (BTU/hr).
