Electric Radiator Wattage Formula:
| From: | To: |
The Electric Radiator Wattage Calculator converts thermal heating capacity (BTU/h) to electrical input power (watts) assuming 100% efficiency. This helps determine the electrical requirements for electric heating systems based on their thermal output.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts thermal output to electrical input, assuming perfect efficiency in the conversion process.
Details: Accurate wattage calculation is essential for proper electrical system design, circuit sizing, energy consumption estimation, and ensuring electrical safety for heating installations.
Tips: Enter the heating capacity in BTU/h. The value must be greater than zero. The calculator will provide the equivalent electrical power in watts.
Q1: Why is the conversion factor 3.412?
A: 3.412 is the exact conversion factor where 1 watt = 3.412 BTU/h, based on the definition of these units.
Q2: Does this assume 100% efficiency?
A: Yes, this calculation assumes perfect conversion efficiency. Real-world systems may have lower efficiency due to heat loss and other factors.
Q3: What is a typical BTU/h rating for electric radiators?
A: Residential electric radiators typically range from 1,000 to 5,000 BTU/h, corresponding to approximately 293 to 1,465 watts.
Q4: How accurate is this conversion for real-world applications?
A: The conversion is mathematically exact, but actual electrical requirements may vary based on system efficiency, voltage fluctuations, and environmental conditions.
Q5: Can this be used for other heating appliances?
A: Yes, this conversion applies to any electric heating device where you need to convert between thermal output (BTU/h) and electrical input (watts).
