What is a Kilowatt Hour (kWh)?

**The Kilowatt Hour (kWh) it is unit of measurement used to measure electricity consumption.** Therefore, for anyone really interested in knowing how much electricity is being used at home and what is the electricity cost, to know what a Kilowatt Hour is it is a must-to-have knowledge.

As shown in the picture below, this household is using an average of 2700 kWh and it is being charged 0,2173 euro per kWh. Multiplying the 2700 kWh by 0,2173 per kWh gives us an electricity cost of nearly 600 euro per year. Let’s note that there are some fix costs that are also charged to the consumers.

One Kilowatt (kW) it is the equivalent to 1000 Watts (W) so, for example, if we have a 60 Watts bulb and we want to find the equivalent in Kilowatt we just need to divide 60 by 1000 and that gives us a power consumption of 0,06 Kilowatts. 60 W /1000 = 0,06 kWh If we want to know the Kilowatts hour are used by that bulb over a period of 10 hours we just need to multiply 0,06 by 10 and that gives us a total of 0,6 Kilowatt Hours (kWh) 0,06 kWh x 10 hours = 0,6 kWh Watt (W), Kilowatt (kW), and Kilowatt Hour (kWh) relationship For those who are interested on some additional knowledge about this topic, have a look to the video below from the **Youtube Effiworkx channel**. https://www.youtube.com/channel/UCSgS-zXti7dq7j_oOwfdFjQ In this video we are explaining how Watts (W), Kilowatts (kW) and Kilowatt Hours (kWh) are related and how this knowledge translates into useful applications like deciding if purchasing a more energy efficient appliance it is really cst effective. We are working towards make the videos available in many languages so if English is not your main language have a look to the channel for other language options. https://youtu.be/CdzJJg0xRaM If you want to know more about electricity saving opportunities, visit us at Effiworkx and let us walk you though the home efficiency path https://effiworkx.com/electricity/
