In my room there's a small aircon, it is 12000BTU. I know there are some bigger ones which can be 18000 or 24000 BTU.
BTU is a unit to measure heat value, which is similar to calorie or joule. So why do they use a heat value unit to show the power of an aircon, but not a power unit such as kW or horsepower.
Thanks for reading.
