| From: | To: |
The kW to BTU/hr conversion calculates British thermal units per hour from kilowatts. This conversion is essential for comparing and converting between different power measurement systems, particularly in heating, ventilation, and air conditioning (HVAC) applications.
The calculator uses the conversion formula:
Where:
Explanation: One kilowatt is equivalent to 3412.142 British thermal units per hour, making this a straightforward multiplication conversion.
Details: Accurate power conversion between kW and BTU/hr is crucial for HVAC system design, energy efficiency calculations, and equipment specification in both residential and commercial applications.
Tips: Enter power value in kilowatts. The value must be a positive number. The calculator will instantly convert it to British thermal units per hour.
Q1: Why is the conversion factor 3412.142?
A: This factor comes from the definition of BTU and watt relationships. 1 kW = 1000 watts, and 1 watt = 3.412142 BTU/hr, so 1 kW = 3412.142 BTU/hr.
Q2: When would I need to convert kW to BTU/hr?
A: This conversion is commonly used in HVAC industry for sizing heating and cooling equipment, where BTU/hr is the standard unit for capacity measurement.
Q3: Is the conversion factor exact?
A: The factor 3412.142 is a standard conversion value used in engineering calculations, though some references may use slightly rounded values like 3412.
Q4: Can this calculator handle decimal values?
A: Yes, the calculator accepts decimal values for more precise conversions, which is important for accurate equipment sizing.
Q5: Are there different types of BTU measurements?
A: While there are different historical definitions, the International Table BTU (IT BTU) is most commonly used in these conversions and is what this calculator employs.
