Room BTU Calculator
Estimate air-conditioner cooling capacity. Use Tinkkit’s free room btu calculator directly in your browser.
Tip from Tink: Insulation, climate and sunlight affect actual cooling demand.
Cooling capacity
4,400 BTU/h
Cooling power
1.26 kW
Rough estimate only: baseline 20 BTU/h per ft² plus 600 per occupant beyond two. Increase factor for hot, sunny or poorly insulated rooms. Not a heating-load calculation.
