1. What is BTU to Watts Conversion?

The BTU (British Thermal Unit) to Watts conversion is used to convert power measurements between imperial and metric systems. BTU per hour measures thermal power, while watts measure electrical and mechanical power.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( BTU/h \) — British Thermal Units per hour
• \( 0.29307107 \) — Conversion factor (exact value)
• \( Watts \) — Result in watts

Explanation: One BTU per hour equals approximately 0.293 watts. This conversion factor is derived from the definition of BTU and watt units.

3. Importance of Power Conversion

Details: Accurate power conversion is essential for HVAC system design, electrical engineering, energy efficiency calculations, and international equipment specifications.

4. Using the Calculator

Tips: Enter BTU per hour value in the input field. The calculator will automatically convert to watts. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The exact conversion factor is 0.29307107 watts per BTU/hour.

Q2: Why convert BTU/h to watts?
A: This conversion is useful for comparing heating/cooling systems with electrical systems and for international standards compliance.

Q3: Is BTU/h the same as BTU?
A: No, BTU is a unit of energy, while BTU/h is a unit of power (energy per time). 1 BTU/h equals the power needed to heat/cool 1 pound of water by 1°F per hour.

Q4: What are common applications?
A: HVAC system sizing, generator capacity planning, energy efficiency calculations, and international equipment specifications.

Q5: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions, providing precise results for engineering applications.
