BTU to Watts Conversion Formula:
From: | To: |
The BTU (British Thermal Unit) to watts conversion is used to convert thermal energy measurements to electrical power equivalents. This conversion is essential for comparing heating/cooling systems and electrical appliances.
The calculator uses the conversion formula:
Where:
Explanation: One BTU per hour equals approximately 0.293 watts, making this conversion essential for energy calculations between different measurement systems.
Details: This conversion is crucial for HVAC system sizing, energy efficiency comparisons, electrical load calculations, and international standards compliance in heating and cooling applications.
Tips: Enter BTU/h value in the input field. The calculator will automatically convert to watts. Default value is set to 18,000 BTU/h for common air conditioning unit conversions.
Q1: Why convert BTU to watts?
A: Conversion allows comparison between thermal energy (BTU) and electrical power (watts), essential for system design and energy efficiency analysis.
Q2: What is 18,000 BTU/h in watts?
A: 18,000 BTU/h equals approximately 5,274 watts, which is a common rating for 1.5-ton air conditioning units.
Q3: Is the conversion factor exact?
A: The factor 0.29307107 is commonly rounded to 0.293 for practical calculations, providing sufficient accuracy for most applications.
Q4: When is this conversion used?
A: Commonly used in HVAC industry, electrical engineering, energy audits, and appliance efficiency ratings.
Q5: Can I convert watts back to BTU?
A: Yes, use the inverse formula: BTU/h = W ÷ 0.293 or multiply by approximately 3.412.
