How This Calculator Works
This BTU (British Thermal Unit) calculator helps you determine the cooling capacity needed for your room. The calculation takes into account:
- Room size: Length × width in square meters
- Ceiling height: Higher ceilings require more cooling capacity
- Sun exposure: West-facing or sunny rooms need more BTU
- Occupants: Each person adds heat to the room
- Kitchen: Cooking appliances generate significant heat
- Climate adjustment: Malaysia's tropical climate requires +25% capacity
