hi
if im using 300w of power (assumming im using 300w)
how many kw an hour am i using in a month ?

If the appliance that consumes 300w is on *24 hours a day, 7 days a week* (which may not be the case) then it (if my memory serves me correctly) would consume 223.2 kwh.

-----------------

E=(300w)(24hrs)(31)
E=223,200 wh / 1000
E= 223.2 kwh

-----------------

I think that's right...
(If It's not then someone correct me...)

found it

kWh = (Watts * Time in Use) / 1000
For monthly use, replace Time in Use with 30 * 24 = 720

So I was right

It just depends on what month you're talking about. Some have 30 days some have 31...

On a 30 day month = 216 kWh
On a 31 day month = 223.2 kWh

Have a good one...
