When buying an 8000 BTU air conditioner, people think about many factors. One of them is, “how many watts does an 8,000 BTU air conditioner use?”

The energy demand of an air conditioner depends highly on its BTU amount. So, you must know the wattage demand accordingly.

In this article, we will answer your question and help you to calculate your energy cost for an 8000 BTU air conditioner.

## How Many Watts Does A 8,000 BTU Air Conditioner Use?

**Generally, 8,000 BTU air conditioners need 800-watt power to run. It can vary according to the brand and the type of your conditioner. **

Depending on the weather, you may need 700-800 watt per hour for using a medium or 8,000 BTU air conditioner.

## How To Determine The Wattage Demand Of Your 8000 BTU Air Conditioner

There are three different methods that can be used to determine how many watts your air conditioner actually uses:

- Check the spec sheet for information regarding Watts. Wattage, which is measured in Watts, can be found in the same area as amperage, which is measured in Ampers, and voltage, which is measured in Volts (in Volts).
- Amperes and volts should both be listed on the specification sheet. The power can be determined by simply multiplying the number of amperes by the number of volts (something like 10A times 120V equals 1,200W, for example).
- To determine the amount of power that your air conditioner consumes, you can use the BTU and EER ratings. You can find the wattage output by dividing the BTU by the EER rating. For example, 5,000 BTU divided by 10 EER equals 500W.

## How To Determine The Monthly Cost Of Operating An 8000 BTU Window Air Conditioner

### Step 1

Check the wattage of the air conditioner, which refers to the amount of electricity that is consumed by the equipment in one hour.

This number may be printed on the side of the product, on a tag that is attached to the electrical cord, or it may be included in the instruction manual.

You can come across amps rather than watts.

If this is the case, the watts can be calculated by multiplying the amps by the voltage in your nation, which in the United States is 120 volts.

For instance, the wattage may be determined by multiplying the unit’s current, which is 7.0 amps, by the voltage, which is 120 volts, which results in 840 watts.

Alternatively, if the device has an EER, you can calculate the watts of the device by dividing 8,000 by the EER.

As an illustration, a unit that has an EER of 10.8 and a capacity of 8,000 BTU consumes 740 watts.

### Step 2

Locate your cost per kilowatt-hour, often known as kW, of power by checking your most recent electric statement.

It’s possible that, in order to calculate your overall cost per kilowatt-hour, you’ll need to tally up the individual prices for supply and delivery first.

### Step 3

To convert the watts of the air conditioner to kilowatts, divide the total number of watts by 1,000.

For instance, the power output of an air conditioner rated at 840 watts would be expressed as 840 divided by 1,000, or 0.84 kW.

### Step 4

To calculate how much it will cost to run your air conditioner for one hour, multiply the kW by the cost per kilowatt-hour.

If your electricity costs 11.1 cents per kilowatt-hour, for instance, you would multiply 0.84 kW by $0.111, which would give you a total of $0.09324 per hour, which is equivalent to 9.324 cents per hour.

### Step 5

Calculate the number of hours that your air conditioner will be on each day, multiply that number by 30, and you will have an approximation of the number of hours that it will be on each month.

Multiplying the amount of time you expect to have the air conditioner on by the number of days in a month gives you an estimate of the total number of hours it will run each month.

To determine how much it costs to run your air conditioner every month, take the amount you calculated earlier for the cost per hour and multiply it by the number of hours in a month.

The total cost for an air conditioner that costs $0.09324 per hour to run and is used for a total of 90 hours per month is $8.39 every month.

## FAQs

### Why Are Watts Essential For Air Conditioners?

You are familiar with watts from the household lightbulbs you use. Typically, a higher wattage corresponds to a brighter light, but additional lighting consumes more energy, resulting in higher utility costs.

On a far greater scale, the same notion applies to heating and air conditioning. Watts are a good starting point for determining how long it will take to see a return on your investment

### How Do Watts Apply To Air Conditioning?

When analyzing genuine energy efficiency, the rate at which your home’s cooling system utilizes energy to keep you comfortable is crucial information.

Using the watts in conjunction with the amps and volts provides a fair grasp of how many kilowatt-hours are required to operate the device.

If the item is not marked with watts, multiply the voltages and amps and convert the result to kilowatts per hour.

Using your electric company’s rates, you can then calculate how much it will cost each hour to operate the unit.

### What Is The Relation Between BTUs And Watts?

BTUs are another statistic listed on modern air conditioning systems for Southern California homes.

One BTU is equal to the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

There are approximately 3,41 BTUs per watt, so to calculate watts, divide the BTUs by this figure.

### What Is The Relation Between Watts, BTUs, And The SEER Rating Of An Air Conditioner?

If the AC system’s label displays the SEER rating and BTUs, calculating watts is somewhat simplified.

The result of dividing the amount of BTUs by the SEER rating is the number of watts.

Then, you may convert that to kilowatts and use your electric company’s rate to establish a baseline for summertime operation.

### What Is The Energy Consumption Of A Central Air Conditioner?

Depending on the local environment, the watts per hour allocated to a central air conditioning system will vary.

In general, central air conditioning uses between 3,000 and 3,500 watts per hour.

Warmer climes may have a larger range of AC watts because the air is warmer, but the home’s insulation may be more effective and better able to trap cold air, allowing the usage of a fan-only mode.

### Where Can Watt Ratings Be Found?

Frequently, the wattage of an air conditioner can be found in the manual that comes with a newly purchased device.

The information may also be available on the manufacturer’s website or upon request to help you make an informed choice.

## Final Thoughts

Now you know the answer to the question, how many watts does an 8,000 BTU air conditioner use?

It is 800 watts in general. However, the demand can vary according to the various air condition type and changing weather.

We hope our given information will highly help you to calculate the wattage and the cost.

Take effective steps to lower your wattage demand and cost as much as possible.
