As an electricity measurement unit, the Kilowatt measures the power used by larger home appliances.
For example, the electricity usage of a fridge, freezer, washing machine, or tumble dryer is measured in kWh.
So, to know how to reduce electricity usage and the electricity bill, you need to learn what a Kilowatt is.

A Kilowatt (kW) is a unit used to measure power.
A Watt (W) is the amount of energy our household appliances and devices need to function, the rate at which they consume energy.
And one Kilowatt is equivalent to 1000 watts.
1kW = 1000 W
The following video explains a Kilowatt and how it relates 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 and explanations.
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, we need to know how much that is in Watts:
3.75 kW / 1000 = 3750 W
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 the electricity suppliers use to calculate our electricity bills.
Also, most big appliances, like 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
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
Here are a few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
If you want to know how many Kilowatts an appliance or device uses, your best option is to use a plug-in power meter to measure the electricity consumption.
Clicking on the image below will redirect you to the Amazon page, where you can look at the specifications of the power meter we use for our measurements.
Our house appliances and devices like the washing machine, the dishwasher, the TV, or the printer are plugged into 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 time.

A kilowatt is equal to 1000 watts.
In terms of money, the cost of a kilowatt hour depends 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, a small electric fan uses around 50 Watts an hour, so it will take 20 hours to use one kilowatt.
Instead, an air conditioner can use around 1500 Watts an hour, so using one kilowatt will take less than one hour.
There are 1000 Kilowatts in a Megawatt.
1 MW = 1000 kW
The power consumption, kilowatts, of a house depends on the number of appliances and devices that a house has and some other factors. For example, does the house use electricity for heating? Or, how many people live in the house?
For example, per the picture below, an apartment of 90 square meters where four people live used 3456 kWh in one year.
This is 9.46 kWh per day or 0.4 kWh per day on average.
This means that this apartment, for its particular conditions, needs an average of 0.4 Kilowatts every hour.
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 for your energy bills.
And it also benefits the environment because conserving electricity prevents unnecessary waste of natural resources.
At the individual level, it may not look worth trying to save a few watts here or there.
Still, every little one counts, and if hundreds or thousands of us save a little every time, it will make an essential contribution towards conserving our natural resources.
For example, if 9000 households save as little as 10 Watts per day (0,01 kWh), that would save 32850 Kilowatt hours (kWh) annually.
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 euros (or dollars, pounds, or any other currency) per kWh, we would collectively save nearly 6000 euros annually.
> 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.
In any case, small energy savings do count when looking into the bigger picture.
