Air Conditioner BTU Sizer is a verified engineering & build calculation tool on Calcify. Calculate required Air Conditioner cooling capacity in BTU/hr and Tonnage (TR) for any room. All calculations execute locally in your browser with multi-currency support, visual breakdowns, and white-label client exports.
Calculated Thermal Load: 1.18 TR (4.14 kW cooling)
Total_BTU = [ (Area_SqFt × 65) + (Extra_Occupants × 600) ] × Thermal_Factor; Tons (TR) = BTU / 12,000
Example Inputs: Room Floor Area (Sq.Ft.): 180 Sq.Ft. · Average Number of Occupants: 3 People · Thermal Exposure / Floor Level: 1.15
Example Output: Recommended AC Tonnage & BTU: 1.5 Ton (14,145 BTU/hr) (Calculated Thermal Load: 1.18 TR (4.14 kW cooling))
The Air Conditioner BTU Sizer on Calcify applies the verified mathematical formula: Total_BTU = [ (Area_SqFt × 65) + (Extra_Occupants × 600) ] × Thermal_Factor; Tons (TR) = BTU / 12,000. Every input is validated in real time with multi-currency formatting to ensure zero rounding or division errors.
1 Ton of Refrigeration (TR) equals 12,000 BTU/hr (~3.517 kW thermal cooling).
