The conversion between British Thermal Units per hour (BTU/h) and watts (W) is essential for comparing power measurements between imperial and metric systems. This conversion is commonly used in heating, ventilation, and air conditioning (HVAC) applications.
The calculator uses the conversion formula:
Where:
Explanation: One watt is equal to approximately 3.412142 BTU/h, making the conversion factor 0.293071 for converting BTU/h to watts.
Details: Accurate power unit conversion is crucial for international engineering projects, equipment specification, energy efficiency calculations, and comparing performance data across different measurement systems.
Tips: Enter BTU/h value (must be greater than 0). The calculator will automatically convert to watts with precision to four decimal places.
Q1: Why is the conversion factor 0.293071?
A: This factor comes from the definition that 1 watt = 3.412142 BTU/h, so the reciprocal (1/3.412142) equals approximately 0.293071.
Q2: What are common applications for this conversion?
A: HVAC system sizing, electrical appliance power ratings, energy efficiency comparisons, and international equipment specifications.
Q3: Is BTU/h the same as BTU?
A: No, BTU is a unit of energy, while BTU/h is a unit of power (energy per time). This calculator converts power units.
Q4: How accurate is this conversion?
A: The conversion factor 0.293071 provides high accuracy for most practical applications, though extremely precise scientific calculations might use more decimal places.
Q5: Can I convert watts back to BTU/h?
A: Yes, to convert watts to BTU/h, multiply the watt value by 3.412142 (the inverse of 0.293071).
