Air Conditioner BTU Calculator
Result
Air Conditioner BTU Calculator The Air Conditioner BTU Calculator estimates the cooling capacity (in BTU/hr) needed to cool a room, based on its dimensions, climate, sun exposure and number of occupants. It also converts the result into tonnes of cooling — free online calculator.
Formula
- Air Conditioner BTU Calculator calculates its result from Sunfactor, Climatefactor, Occupants, Height, Length, Width. It uses the formula BTU = Length × Width × Height × 300 × ClimateFactor × SunFactor + (Occupants−2) × 600. Change any input to recalculate the result instantly.
- The main inputs are Room Length, Room Width, Ceiling Height, Climate, Sun Exposure, Occupants. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Air Conditioner BTU
- Room Length: 5
- Room Width: 4
- Ceiling Height: 3 m
- Climate: hot
- Sun Exposure: average
- Occupants: 2
Using Sunfactor = 2, Climatefactor = 3, Occupants = 4, Height = 5, Length = 6, Width = 7, the calculated result is 379200.
