Conversion Formula:
From: | To: |
The Watts to BTU/hr conversion calculates the equivalent power in British Thermal Units per hour from a given value in Watts. This is commonly used in heating, ventilation, and air conditioning (HVAC) systems and energy calculations.
The calculator uses the conversion formula:
Where:
Explanation: One watt is equal to approximately 3.41214 BTU per hour. This conversion factor remains constant regardless of the wattage value.
Details: Accurate power conversion is essential for comparing energy systems, sizing HVAC equipment, and understanding energy efficiency across different measurement systems.
Tips: Enter power in watts (must be a positive number). The calculator will instantly provide the equivalent value in BTU/hr.
Q1: Why convert watts to BTU/hr?
A: BTU/hr is commonly used in heating and cooling applications in the US, while watts are the SI unit of power. Conversion allows comparison between systems using different units.
Q2: Is the conversion factor exact?
A: The factor 3.41214 is based on the International Table BTU, which equals exactly 1055.05585262 joules.
Q3: Can this be used for large power values?
A: Yes, the conversion factor scales linearly for any wattage value from very small to very large.
Q4: How does this relate to energy efficiency?
A: Converting between units helps compare the efficiency of devices rated in different units (e.g., electric heaters in watts vs gas heaters in BTU/hr).
Q5: What about other power units?
A: For other conversions (e.g., kW to BTU/hr), first convert to watts then apply this conversion factor.
