Built for Malaysian Conditions
Unlike generic BTU calculators, this tool applies a 1.25× tropical adjustment — standard for Malaysia's year-round heat and humidity. Generic calculators (built for temperate climates) will recommend units that are too small.

What does BTU mean?
BTU stands for British Thermal Unit — it measures cooling or heating capacity. Higher BTU = more cooling power. In Malaysia, aircon units are typically described in horsepower (HP), which is roughly 9,000 BTU = 1 HP.
Why does Malaysia need a tropical adjustment?
Malaysia's year-round temperatures (30–35°C) and high humidity mean rooms require approximately 25% more cooling capacity than equivalent rooms in temperate climates. Generic calculators often undersize your unit.
Is a bigger HP always better?
No. Oversized units cycle on and off too frequently, which wastes energy and doesn't dehumidify the air properly. The right size for your room is always the best choice. Our calculator gives you the accurate minimum required.
