BTU to Tons Conversion Formula:
| From: | To: |
The BTU to Tons conversion is used in HVAC (Heating, Ventilation, and Air Conditioning) systems to convert British Thermal Units per hour to refrigeration tons. One ton of refrigeration equals 12,000 BTU per hour.
The calculator uses the conversion formula:
Where:
Explanation: This formula converts cooling capacity from BTU per hour to refrigeration tons, which is the standard unit for air conditioning and refrigeration systems.
Details: Accurate conversion between BTU/hr and tons is essential for proper sizing of HVAC equipment, energy efficiency calculations, and system design in residential, commercial, and industrial applications.
Tips: Enter BTU per hour value in the input field. The value must be greater than 0. The calculator will automatically convert to tons with four decimal places precision.
Q1: What is a refrigeration ton?
A: One ton of refrigeration is the amount of heat required to melt one ton (2000 pounds) of ice in 24 hours, equivalent to 12,000 BTU per hour.
Q2: Why is this conversion important for HVAC systems?
A: Proper sizing of air conditioning units requires accurate tonnage calculation to ensure efficient cooling and prevent system overload or underperformance.
Q3: What are typical tonnage values for residential AC units?
A: Residential units typically range from 1.5 to 5 tons, with 1 ton cooling approximately 400-600 square feet depending on insulation and climate.
Q4: Can this calculator be used for heating systems?
A: While primarily for cooling, the conversion can be used for heat pump systems where both heating and cooling capacities are measured in similar units.
Q5: What factors affect the actual cooling capacity needed?
A: Room size, insulation quality, number of windows, ceiling height, climate, number of occupants, and heat-generating appliances all affect cooling requirements.
