Understanding Watt

Watt is a unit of power. Most of your electric appliances have wattage unit details in its specification label. Watt is denoted by “W”. And you must have used or heard this word while asking for a 40W tube light or 20 W LED light, 1000W room heater.

So in short, Power (KW) X Time (T) = Electricity (Energy)

Understanding Watt (W) and kilowatt (KW)

Most of you know the relation between meter (M) and kilometer (KM), right?

Understanding Watt, Kilowatt and Unit of Electricity

1 KM = 1000M

Do you remember the TV ad which says “Kitna Deti Hai”, there he meant with efficiency of Yacht. You must also know your bike/car mileage. Similar is the case with your appliances.  How much your appliance runs by consuming a unit of electricity? Before understanding that, we need to understand what we mean by a unit of electricity?

1 unit of electricity = 1KWH = appliance of 1000 W running for 1 Hr.

 An appliance with 100W can run for 10 Hrs. in one unit, similarly, an appliance of 10 W can run for 100 hrs.

Electricity Unit and Appliance wattage

An electricity unit is one that is represented in your house electricity bill or in other words what your electric meter installed in your house shows in numbers. 1 unit of your electricity in your energy bill is equivalent to the kilowatt-hour.

So if you use 100 watt bulb in your house for 10 hours that means

100 X 10 = 1000 watt-hour =1Kilowatt-hour (KWH)

Since 1000 watt = 1Kilowatt

Then, 1Kilowatt-Hour = 1 unit of electricity on your energy meter or energy bill.

How to estimate units consumed by your appliance in your home

After discussing most of the basic concepts, it is now time to take the next step of calculating your approximate daily electricity unit’s consumption. First of all prepare the list of appliances along with their installed numbers, wattage and estimated usage. You may easily find wattage (w) value in the label of your appliance.

In the table, which has been prepared for your reference, you can see the list of appliances that an Indian citizen holds in his 2-BHK flat. However you may change the numbers of installed appliances, wattage, and hours of usage to check your expected energy units and monthly bill.

Please note that units of electricity that you get from the above calculation are only for representation purpose and will give approximate units of electricity consumption. Many other factors like power factor of your appliance, amount of time your appliance actually worked, for example, some of your appliances like AC, fridge, Iron don’t run continuously, these undergo auto on-off cycle. However, the above calculation will give you an idea of the consumption band you are falling in and which appliance has a maximum share on your bill.

Note: If you have a 1HP motor in your home then you can calculate as follow:

1HP= 746 watt=0.746KW

This means that your 1 HP pump or motor will consume 0.746 units of electricity per hour of operation.

Conclusion

With these articles, we have tried to link all the basic concepts relating watt to kilowatt, kilowatt to kilowatt-hour, and kilowatt-hour to units of your meter, with all these relations you can easily relate between watt to a unit of electricity.

After going through the article “Understanding Watt, Kilowatt and Unit of Electricity with us”, you must be capable enough to get your house approximate consumption, however, in case you need help, feel free to comment below.
