Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Hi,
I was wondering if it is possible to convert from KWH/day to MJ/hr?
The issue I am having is with the KWH.......
Any advice would be appreciated.
Thanks

A Joule is 1 Ws. So a kWh is 1000 W and 3600 s which is 3.6 MJ. 3.6 MJ/day is 3.6/24 MJ/h = 0.15 MJ/h.

However, energy/time is power, so the measure would be best expressed in watts (W). 1 kWh/day is 1000/24 Wh/h = 41.67 watts.

1 kWh is 1 kW for 1 hour. 1 hour = 3600 s, and 1 watt = 1 joule per second.

So the 1 kW = 1 kJ/s,

1 kWh = (1 kJ/s) x (3600s/h x 1 h) = 3.6 MJ
(the parentheses are unnecessary, but may add clarity)
