BTU to HP Conversion Formula:
| From: | To: |
The BTU to HP conversion is used in air conditioning systems to convert British Thermal Units per hour (BTU/h) to horsepower (HP) or tons of refrigeration. This conversion helps in sizing and selecting appropriate air conditioning units for various applications.
The calculator uses the conversion formula:
Where:
Explanation: One ton of refrigeration equals 12,000 BTU per hour, which is equivalent to the cooling capacity needed to melt one ton of ice in 24 hours.
Details: Accurate conversion between BTU and HP is essential for proper air conditioning system sizing, energy efficiency calculations, and equipment selection in HVAC applications.
Tips: Enter BTU value in BTU/h. The calculator will automatically convert to horsepower (tons). All values must be valid (BTU > 0).
Q1: Why is 12,000 BTU/h equal to 1 ton?
A: This comes from the historical definition where one ton of refrigeration represents the heat absorption required to melt one ton of ice in 24 hours.
Q2: What is the difference between HP and tons in air conditioning?
A: In air conditioning context, 1 HP typically equals 1 ton of refrigeration capacity, both representing approximately 12,000 BTU/h.
Q3: How do I determine the BTU requirement for my space?
A: BTU requirements depend on room size, insulation, number of occupants, windows, and climate. Professional HVAC calculations are recommended.
Q4: Can this conversion be used for heating systems?
A: While the principle is similar, heating systems may use different conversion factors. This calculator is specifically designed for air conditioning applications.
Q5: What are common air conditioner sizes in tons?
A: Common residential AC units range from 1.5 to 5 tons (18,000 to 60,000 BTU/h), with commercial units going much higher.
