What is a kWh – kilowatt hour + CALCULATIONS 💡💰 energy bill

In this video we learn what a kWh is, the kilowatt hour is used for energy bills and related to the amount of electricity consumed by electrical items. We run through what a kilowatt and a kilowatt hour is as well as watts and joules. We see worked examples at the end for how to calculate kwh consumption and electricity bills.

    I thought kilowatt is 1000 x watts, then what is milliwatt or is there a milliwatt?

    at 1:09 you say the label is how much energy is used per second, then at 2:30 you say its per hour?

    Please .. you said that the heater Watt mean how many joules per (Second) at 1:10 and when you Calculate for 3 hours at 3:08 you multiply 2kw*3 hours direct ! ,, why you didnt convert hours to seconds first ?! sorry it make some confusion to me

    So a watt is measured over 1 second. Why are you skipping to hours.
    Does a 60w light bulb use 60w per second, or 60w per hour?

    I am sure many folks are wondering why electricity seems so cheap in your example. 10 cents a kWh is pretty cheap but if that is what you pay realize in the US anyway, most utility companies tack on all kinds of extra charges (many required by the government and some as a means of passing on other costs). Distribution, transmission (yes, two different things) low income supplement charge etc, etc. By the time you are done, kWh goes up since many are based on your kWh some are flat rate. Expect to see 30 to 35 cents per kWh or where I live a lot more. You did a great job, thank you.

    So, if a generator says its output is 1948kwhr than what will be its power actually??
    And if i want to calculate its actual output for one hour how will i do it?

    at around 2:15 you’ve got some terms back to front.
    1 Kilowatt or KW = 1000 watts, not 1w=1000kw.
    Otherwise great.

    Actually, if you swap your operators it would be fine. swap your division for multiplication.

    I was missing the most important part of information regarding the Kwh, how much work 1 Kwh is. If someone would take a back pack and load it with some drinking water, (he will probably need it) so that he all together weighs 100 kg. How many stairs does he need to climb before he has made the work of 1 Kwh?
    When you know that, you can start to have an idea about what a Kwh is.

    1 kW x 1000 can never = 1000 W

    1 kW = 1000 W

    Sir ,u r awesome. My sincere thanks and gratitude goes to u for putting tremendous effort and hours to explain engineering stuff to us.

    Could u please make a series of videos that shows in steps how to design an HVAC ,plumbing and fire fighting system for a project u have worked on ?
    Nowadays it is harder to land a job in the engineering sector as a fresh graduate. Plz that will make a huge impact in my life if u could give series of training videos on how to design engineering systems such i mentioned above.

    Many thanks to u again

    Thank you so much for the videos! I really enjoy watching them a lot. But I have a question on this video. I don’t know why "KW * 1000 = W"(2:15).Because earlier you said, 1 W = 1 joule, and 1 KW = 1000 joules.Therefore, Is it possible that you meant to say W * 1000 = KW?
