Tonnage Formula:
| From: | To: |
The split AC tonnage calculation converts British Thermal Units per hour (BTU/h) to tons of refrigeration, which is a standard measurement for air conditioning capacity. One ton of refrigeration equals 12,000 BTU/h.
The calculator uses the simple formula:
Where:
Explanation: This formula provides a straightforward conversion from BTU/h to tons, which is essential for proper AC unit sizing and selection.
Details: Correctly sizing an AC unit is crucial for energy efficiency, optimal performance, and comfort. An undersized unit will struggle to cool the space, while an oversized unit will cycle frequently, leading to higher energy costs and reduced humidity control.
Tips: Enter the BTU/h rating of your AC unit. The value must be greater than 0. The calculator will instantly convert it to tons of refrigeration.
Q1: Why is AC capacity measured in tons?
A: The term "ton" in air conditioning refers to the amount of heat required to melt one ton of ice in 24 hours, which equals 12,000 BTU/h.
Q2: What's the typical tonnage for residential AC units?
A: Residential units typically range from 1.5 to 5 tons, with 1 ton generally cooling about 400-600 square feet depending on insulation and climate.
Q3: How do I determine the right BTU for my space?
A: BTU requirements depend on room size, insulation, windows, climate, and other factors. Generally, you need about 20 BTU per square foot of living space.
Q4: Can I use this for all types of AC units?
A: Yes, this conversion applies to all air conditioning systems including split AC, window units, central AC, and heat pumps.
Q5: What's the difference between BTU and tons?
A: BTU (British Thermal Unit) measures energy, while tons measure cooling capacity. One ton equals 12,000 BTU/h, representing the cooling power needed to melt one ton of ice in 24 hours.
