Power Conversion Formula:
From: | To: |
The conversion between watts and BTU/hr (British Thermal Units per hour) is essential for comparing power measurements between different systems, particularly when working with electrical and thermal energy systems.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor allows you to translate electrical power (watts) to thermal power (BTU/hr), which is particularly useful in HVAC systems and energy efficiency calculations.
Details: Accurate power conversion is crucial for system design, energy efficiency calculations, equipment selection, and comparing performance across different measurement systems.
Tips: Enter the power value in watts. The value must be greater than zero. The calculator will automatically convert to BTU/hr using the standard conversion factor.
Q1: Why is the conversion factor 3.412?
A: This value comes from the definition of BTU and watt. 1 BTU equals approximately 1055 joules, and 1 watt equals 1 joule per second, leading to this conversion factor.
Q2: Is this conversion exact?
A: The conversion factor 3.412 is a standard approximation used in engineering calculations. The exact value is 3.412141633, but 3.412 is sufficient for most practical applications.
Q3: When would I need to convert watts to BTU/hr?
A: This conversion is commonly used in HVAC system design, electrical heating calculations, energy efficiency comparisons, and when working with equipment that uses different power measurement systems.
Q4: Can I convert BTU/hr back to watts?
A: Yes, to convert BTU/hr to watts, divide by 3.412 (or multiply by approximately 0.293).
Q5: Does this conversion apply to all types of watts and BTU?
A: Yes, this is a standard power conversion that applies equally to electrical watts, mechanical watts, and thermal BTU/hr measurements.
