The BTU/hr to Watts conversion is used to convert British Thermal Units per hour to electrical power units (Watts). This conversion is essential for comparing heating/cooling capacities with electrical power requirements.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor 3.412 represents the number of BTU per hour equivalent to one Watt of electrical power.
Details: Accurate power unit conversion is crucial for HVAC system design, electrical load calculations, energy efficiency comparisons, and equipment specification across different measurement systems.
Tips: Enter BTU per hour value in the input field. The value must be positive and greater than zero. The calculator will automatically compute the equivalent power in Watts.
Q1: Why is the conversion factor 3.412?
A: 3.412 BTU/hr equals 1 Watt based on the International System of Units definition where 1 BTU equals approximately 1055 Joules and 1 Watt equals 1 Joule per second.
Q2: When is this conversion commonly used?
A: This conversion is frequently used in HVAC industry, electrical engineering, energy management, and when comparing air conditioner capacities with electrical power consumption.
Q3: What is the difference between BTU and BTU/hr?
A: BTU is a unit of energy, while BTU/hr is a unit of power (energy per unit time). BTU/hr indicates the rate of energy transfer or conversion.
Q4: Are there any limitations to this conversion?
A: This conversion assumes standard conditions and may have slight variations in specific applications, but 3.412 is the universally accepted conversion factor for general calculations.
Q5: Can this calculator be used for both heating and cooling applications?
A: Yes, the conversion applies equally to both heating and cooling power measurements since it's a straightforward unit conversion independent of the application.
