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
