BTU to Watts Conversion Formula:
| From: | To: |
The BTU (British Thermal Unit) to Watts conversion is used to convert thermal power measurements to electrical power measurements. This conversion is essential for comparing heating/cooling systems with electrical appliances and for international standardization.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 0.293 represents the exact conversion rate where 1 BTU per hour equals approximately 0.293071 watts.
Details: Accurate power unit conversion is crucial for HVAC system sizing, energy efficiency calculations, international equipment specifications, and comparing different types of heating/cooling systems.
Tips: Enter BTU per hour value in the input field. The value must be greater than 0. The calculator will automatically convert to watts using the standard conversion factor.
Q1: What is the exact conversion factor?
A: The exact conversion is 1 BTU/h = 0.293071 watts. For most practical purposes, 0.293 is sufficiently accurate.
Q2: Why convert BTU to watts?
A: Conversion allows comparison between thermal systems (measured in BTU) and electrical systems (measured in watts), helping with energy calculations and system compatibility.
Q3: What is a typical BTU rating for air conditioners?
A: Residential air conditioners typically range from 5,000 to 24,000 BTU/h. 14,000 BTU/h is common for medium-sized rooms.
Q4: How accurate is this conversion?
A: The conversion is mathematically precise. However, real-world efficiency may vary due to system design, installation quality, and environmental factors.
Q5: Can I use this for heating systems as well?
A: Yes, the conversion works for both heating and cooling systems since BTU/h measures thermal power transfer regardless of direction.
