1. What is Watt to BTU/hr Conversion?

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

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( \text{BTU/hr} \) — British Thermal Units per hour
• \( \text{W} \) — 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 relationship between the two units of power measurement.

3. Importance of Power Unit Conversion

Details: Accurate power unit conversion is essential when working with equipment specifications, energy calculations, or comparing systems that use different measurement units.

4. Using the Calculator

Tips: Enter power value in watts (must be positive). The calculator will automatically compute the equivalent value in BTU/hr.

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 HVAC systems often use BTU/hr.

Q2: How precise is this conversion?
A: The conversion factor 3.412142 is exact, so the calculation is mathematically precise.

Q3: What is a BTU?
A: A British Thermal Unit is the amount of heat required to raise 1 pound of water by 1°F.

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?
