**Determining how many watts a 10000 BTU air conditioner could use as well as understanding the differences in BTU and watts, and the relationship between the two.**

When considering purchasing an air conditioner, one would typically go about it based on the British Thermal Units (BTU) performance it has to offer, as well as the room size.

Knowing how many watts of energy an air conditioner could consume is actually one of the most important factors to consider, especially if you are looking to be mindful of the energy costs for you.

**How much energy or power do air conditioners use?**

In order to determine the amount of power and energy an air conditioner can use, it’s crucial to first understand what the relationship between BTU and the power in watts is.

This can be determined through an Energy-Efficiency Ratio (EER) rating. EER ratings can range between eight EER to 18 EER, which is dependent on the type of air conditioner that is being measured. Central air conditioners have been noted to have the highest EER ratings.

It has also been said that having an air conditioner with a high energy-efficiency and a higher EER rating can pay off in terms of energy consumption by the air conditioner. Should the air conditioner have a low EER rating, then it will most certainly use up more watts in order to power the unit.

**How many watts does a 10000 BTU air conditioner use?**

To answer the question of how many watts a 10000 BTU air conditioner can use, the answer is between 833 to 1 250 estimated watts of energy/power. This estimate is between the EER range of eight to 12.

## Use This Calculator to Compute How Many Watts Does Air Conditioner Use (BTU)

**We used 10 EER in this calculator. **Yours may be different so make sure to check your AC’s EER rating. To manually compute the wattage of your AC, use this simple formula:

- BTU / EER = your AC’s wattage

Type a value in the BTU field to get the power of your AC:

**Important note:** You also need to consider the EER of your brand new AC.

## How to use the Calculator?

**Simply input the BTU you want to convert in the form**. For example, if you input 5,000 BTU air conditioner and the EER is 10, the calculator will automatically convert it to 500 Watts.

**Steps to determine how much your monthly electricity use will be to run your air conditioner**

There are two factors to consider when trying to establish how much it will cost you to run your air conditioner; the first will be to know the cost your electricity company charges per kilowatt of power per hour. The second is knowing the amount of power your air conditioner will be using in order to run in watts.

In order to establish your home electricity cost, it is also important to firstly note that every state, county and city charges varying rates for the use of electricity.

To find out how much one would generally be paying per kilowatt per hour, looking at your most recent electricity bill will provide you with the answer you need. Alternatively, you could physically go to your electricity company website and find the posted rate.

Once you have established the amount of kilowatts per hour you generally pay, you would then need to find out how many electricity watts your air conditioner is using up.

In as much as an air conditioning product will describe the BTU of the air conditioners cooling capacity, not all will use the same amount of electricity to run the device. This is why the best way to determine how many watts your air conditioner will use is to inspect and consult the product manual and look at the specs on the manufacturer’s website.

Once the wattage is determined, you can then combine that number with the price per kilowatt per hour you pay for electricity at home. The result will confirm the amount it will cost you to run your air conditioner.

**Are air conditioners expensive to have and operate?**

Overall, air conditioners can be very expensive to operate due to their high electricity usage. Depending on how many rooms you are attempting to cool, electricity usage will be a factor regardless.

If you are only cooling one room, power usage will be low, but this is also dependent on the size of the room or rooms, should there be more than one. More rooms will lead to a higher HVAC (heating, ventilation and air conditioning) bill.

Another factor to consider when trying to determine how much power your air conditioner is using is to determine the type of appliances you may have in your house. Lighting is one of those.

Minimal lighting can help in contributing a lower percentage of energy usage, whereas having a number of high-wattage lighting, including the wattage of an air conditioner, can result to a huge electricity bill amount.

Making sure to reduce other energy consumption around the house will also help to ease the costs incurred and allow you to utilise your air conditioner in a way that will not have you worried about how massive your power bill will be every month.

So, look into information such as the BTU, watts of energy you already consume and pay for in order to find suitable air conditioning options.
