We would recommend using our btu cooling calculator to determine the specific amount of btus you will need from your air conditioner in order to properly cool your space.
Btu to watts air conditioner.
Each air conditioner or heater is rated to produce a certain number of btus.
One 10 000 btu air conditioner may use 900 watts of electricity while another one uses 1 000 watts.
Many factors go into calculating btus so we have put together a set of tools to help with air conditioner sizing.
The chart below is a great starting point for sizing your ac.

The british thermal unit or btu is an energy unit.
The power consumption of air conditioners averages 318 watts hourly for a 24 000 btu unit in most american households the power draw of a unit that size ranges from 1 800 to 2 500 watts in most cases.
1 watt is approximately 3 412 btu per hour.
The average is only 318 watts because air conditioning units automatically cycle their compressors on off as needed.
A good eer rating for example is 10.
P w p btu hr 0 29307107 p btu hr 3 412141633.
1 btu 1 055 joules 252 calories 0 293 watt hour or the energy released by burning one match.

Air conditioner btu chart.
What is a btu.
If an air conditioner would have a higher eer rating 12 for example the 500w would give us 6 000 btu of cooling effect.
Air conditioner power consumption trumps that of most appliances.
P w 20000 btu hr 3 412141633 5861 42w.
Btu is a measure of energy not power.
So the power p in watts w is equal to the power p in btus per hour btu hr times 0 29307107 and is equal to the power p in btus per hour btu hr divided by 3 412141633.
1 btu hr 0 29307107 w.
Average wattage once running.

It is approximately the energy needed to heat one pound of water by 1 degree fahrenheit.
The relationship between btu and power in watts of an air conditioner is determined by energy efficiency eer rating.
Btu recommendations based on square footage.
Honestly this sentence makes sense only to the british.
15 000 btu rv air conditioner.
Btu and kw air conditioner capacity btu stands for british thermal unit.
It denotes the amount of energy to raise 1 pound of water for 1 degree fahrenheit.
Once the starting wattage requirements are met and air conditioner starts running you can use the watts for other purposes like microwave or refrigerator.
That means that 500w will give us 5 000 btu of cooling effect.
A 9000 btu air conditioner needs start up watts of around 2000 and thus it wont be enough to start the air conditioner.
