1. What is Watts to BTU Conversion?

The conversion between watts and British Thermal Units (BTU) per hour is essential for comparing power measurements between electrical and thermal systems. 1 watt is equal to approximately 3.412142 BTU per hour.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( Q \) — Power in BTU per hour
• \( W \) — Power in watts
• 3.412142 — Conversion factor (1 W = 3.412142 BTU/hr)

3. Importance of Power Conversion

Details: This conversion is particularly important for HVAC systems, electrical heating equipment, and energy efficiency calculations where both electrical and thermal power measurements are used.

4. Using the Calculator

Tips: Simply enter the power value in watts and the calculator will automatically compute the equivalent in BTU per hour. The input must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 3.412142?
A: This exact value comes from the definition of 1 BTU as approximately 1055.06 joules and 1 watt as 1 joule per second.

Q2: Is this conversion the same for all types of BTU?
A: Yes, this uses the International Table BTU (IT BTU), which is the most commonly used definition in engineering.

Q3: Can I convert BTU/hr back to watts?
A: Yes, simply divide the BTU/hr value by 3.412142 to get watts.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between the units.

Q5: Does this calculator work for large values?
A: Yes, it works for any positive value from very small to very large power measurements.
