AC BTU & Cooling Power for 30 m² Room (16072 BTU/h — 4.71 kW)

Calculate how many BTU/h, kW and frigories you need to cool a room based on area, ceiling height, solar orientation and insulation.

Room Floor Area (m²)

Ceiling Height (Meters)

Insulation & Sun Exposure

Est. Electrical Input1.140 W

Conversion Formulas Between BTU/h, Kilowatts (kW) and Frigories

HVAC Standard (ASHRAE & EN 14511): 1,000 BTU/h equals 0.293 kW of thermal cooling capacity (1 Ton of refrigeration = 12,000 BTU/h = 3.517 kW).

1,000 Frigories/h = 1.163 kW thermal = 3,968.3 BTU/h
Base Cooling Load = (Area m² × Height m × Thermal Factor) + (Occupants × 150 fg)
