1. What is Watt to BTU Conversion?

The Watt to BTU conversion is used to convert power measurements between the metric unit (watt) and the imperial unit (British Thermal Unit per hour). This conversion is commonly used in heating, ventilation, and air conditioning (HVAC) systems.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( \text{BTU/hr} \) — British Thermal Units per hour
• \( \text{W} \) — Watts (power in metric system)
• 3.412142 — Conversion factor (exact value)

Explanation: One watt is equal to approximately 3.412142 BTU per hour. This conversion factor is derived from the definition of BTU.

3. Importance of Power Unit Conversion

Details: Accurate power conversion is essential for engineers, HVAC technicians, and energy professionals who work with equipment specifications in different unit systems.

4. Using the Calculator

Tips: Enter power in watts (W) to get the equivalent in BTU/hr. The input must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between watts and BTU/hr?
A: Different industries use different units - electrical systems typically use watts while heating systems often use BTU/hr.

Q2: Is the conversion factor exact?
A: Yes, 1 W = 3.412142 BTU/hr is an exact conversion based on the definition of BTU.

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

Q4: How accurate is this calculator?
A: It uses the exact conversion factor, so results are mathematically precise.

Q5: Can I convert BTU/hr back to watts?
A: Yes, divide BTU/hr by 3.412142 to get watts.
