Conversion Formula:
| From: | To: |
The kW to BTU/h conversion calculates British thermal units per hour from kilowatts. This conversion is essential for comparing power measurements between different unit systems, particularly in heating, ventilation, and air conditioning (HVAC) applications.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts power measurements from the metric system (kilowatts) to the imperial system (British thermal units per hour).
Details: Accurate power unit conversion is crucial for international engineering projects, HVAC system design, energy efficiency calculations, and equipment specification across different measurement systems.
Tips: Enter power value in kilowatts (kW). The value must be non-negative. The calculator will automatically convert to British thermal units per hour (BTU/h).
Q1: Why is the conversion factor 3412.142?
A: This factor comes from the definition of BTU (amount of energy needed to heat 1 pound of water by 1°F) and the relationship between energy and power units over time.
Q2: What are typical applications for this conversion?
A: HVAC system sizing, boiler capacity calculations, air conditioning unit specifications, and energy consumption comparisons between different measurement systems.
Q3: How accurate is this conversion?
A: The conversion factor 3412.142 provides high accuracy for most engineering and technical applications. For extremely precise scientific calculations, additional decimal places may be used.
Q4: Can I convert BTU/h back to kW?
A: Yes, to convert BTU/h to kW, divide the BTU/h value by 3412.142 (kW = BTU/h ÷ 3412.142).
Q5: Are there different types of BTU measurements?
A: While the basic definition is consistent, some contexts may use International Table BTU (IT BTU) or other variations, though the difference is minimal for most practical applications.
