BTU to Watts Formula:
From: | To: |
The BTU (British Thermal Unit) to Watts conversion is used to translate power measurements between the imperial system (BTU/hr) and the metric system (Watts). This is particularly important in heating, ventilation, and air conditioning (HVAC) applications.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts BTU per hour to Watts by dividing by the conversion factor of approximately 3.412142.
Details: Accurate power unit conversion is essential when working with international equipment specifications, energy efficiency calculations, and comparing systems that use different measurement standards.
Tips: Enter the BTU/hr value you want to convert. The value must be positive. The calculator will automatically compute the equivalent power in Watts.
Q1: Why is the conversion factor 3.412142?
A: This factor comes from the definition of BTU and Watt. 1 BTU is approximately 1055.06 Joules, and 1 Watt is 1 Joule per second. The hourly factor brings it to 3.412142 BTU/hr per Watt.
Q2: Can I use this for cooling capacity as well as heating?
A: Yes, the conversion works the same for both heating and cooling capacities when expressed in BTU/hr.
Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on the defined relationship between the units.
Q4: What's the difference between BTU and BTU/hr?
A: BTU is a unit of energy, while BTU/hr is a unit of power (energy per time). This calculator converts power units.
Q5: When would I need to convert BTU/hr to Watts?
A: Common scenarios include comparing HVAC system specifications, calculating electrical requirements for heating systems, or working with international standards.
