Homework Help: Conversion of enerygy really simple

  1. Apr 4, 2013 #1
    The energy to run a house is 50000watthours/day I want to find out how much energy it takes to run the house in 24 hours. I believe I just simply multiply 5000*24 to get the energy need to run the house the whole day. Because I am reading this as I am running the house for 24 hours in one day. therefore i get 1200000 joules of energy to run the house for the whole day. Is this correct I have a hard time with this per thing.

    Just a guess, but try using dimesional analysis:

    50000 W*h/day * y days/z hours = x Watts

    How can you find Joules from watts?
