Kilowatt conversion calculator

As electricity measurement unit, the Kilowatt is the measurement unit used to measure the power used by the larger home appliances. 

For example, the electricity usage of a fridge, freezer, washing machine or tumble dryer is measured in kWh.

So, if you are interested to know how to reduce the electricity usage and the electricity bill, you need to learn what a Kilowatt is.

What is a Kilowatt

A Kilowatt (kW) it is a unit used to measure power.

A Watt (W) it is the amount of energy that our household appliances and devices need to function, the rate at which they consume energy.

And one Kilowatt it is the equivalent to 1000 watts.

1kW = 1000 W

The following video explains what a Kilowatt is and how it is related to other power measurement units and our household appliances and devices. Do not forget to enable the video captions, as the video caption contains the concepts explanations.

What is a Kilowatt hour (kWh)

Conversion calculator to convert Kilowatts to other units

Kilowatt (kW) to Watt (kW) conversion calculator

To convert Kilowatts (W) to Watts (kW) you need to divide the number of Watts by 1000.

kW = W/1000

 

For example, if a device uses 3.75 Kilowatts but we need to know how much is that in Watts:

3.75 kW / 1000 = 3750 W 

Kilowatt (kW) to Kilowatt hour (kWh) conversion calculator

To convert Kilowatts (kW) to Kilowatt hours (kWh) you need to multiply the number of Kilowatts by the number of hours.

kWh = kW x Hours

kWh is the measurement unit used by the electricity suppliers to calculate our electricity bills. 

Also, most of the big appliances, like the dishwashers or washing machines, rate their consumption in kWh.

 

For example, if a device uses 2.5 Kilowatts and has been working for 5 hours:

2.5 kW x 5 hours = 12.5 kWh 

Kilowatt (kW) to Megawatt (MW) conversion calculator

To convert Kilowatts (W) to Megawatts (MW) you need to divide the number of Kilowatts by 1000.

MW = kW/1000

 

For example, to convert 25 Kilowatts to Megawatts:

25 kW / 1000 = 0.025 MW

A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:

Kilowatt electricity usage monitor

If you want to know how many Kilowatts does an appliance or device use, your best option is to use a plug in power meter to measure the electricity consumption. 

Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.

plug in power meter

All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket. 

So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.

If you want to find out how you can use a plug in power meter to measure your electricity usage and electricity cost, have a look to this YouTube video.

Kilowatt FAQ

How many watts is a kilowatt

A kilowatt is equal to 1000 watts.

How much is a kilowatt of electricity

In terms of money, the cost of a kilowatt hour depend on where you live or even the contract you have with the electricity provider. For example, in Germany in 2021 the average cost per kilowatt hour is 33 cents.

In terms of quantity, an small electric fan uses around 50 Watts an hour so it will take it 20 hours of use to use one kilowatt.

Instead, an air conditioner can use around 1500 Watts an hour so it will take less than one hour of use to use one kilowatt.

How many Kilowatts there are in a Megawatt

There are 1000 Kilowatts in a Megawatt.

1 MW = 1000 kW

How many Kilowatts does a house use

The power consumption, kilowatts, of a house depends on the amount of appliances and devices that a house have, as well as some other factors. For example, does the house use electricity for heating. Or, how many people lives in the house.

As an example, as per the picture below, an apartment of 90 square meters where four people lives did use 3456 kWh in one year.

This is 9.46 kWh per day or 0.4 kWh per day in average.

This means that this apartment, for its particular conditions, needs an average of 0.4 Kilowatts every hour.

Kilowatt and energy conservation

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment 

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.

Energy conservation calculator

 

For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) that would add to 32850 Kilowatt hour (kWh) saved per year. 

9000 households x 0,01 kWh per day x 365 days per year 

32,850 kWh saved per year

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro per year.

> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.

Have a look to this page for more information about the amount of resources needed to produce electricity.
 

In any case it is clear that small energy savings do really count when looking into the bigger picture.
