Question

How does the conversion from (kw H) to MJ work?

Answer 1

I'm working on a thermodynamics problem, and I used WolframAlpha to obtain the conversion from kw H to Megajoules. This made the problem very easy, but I'm not sure how to obtain that conversion.

Answer 2

1 W = 1 J/s

1 kWh=1000 J \(*\sf \dfrac{60~sec}{1~min}*\dfrac{60~min}{1~h}= 3.6*10^6 ~Ws=3.6*10^6 ~J\)

Answer 3

not 1000 J, i meant 1000 W**

Answer 4

Ahhhhhh! Thank you! I see it now.

A Joule is a watt-second, kiloWatt is 1000 watts, .... okay. That should have been much more obvious to me, but anyway thank you! That helps a lot.

Answer 5

good stuff! no problem
