1 kwh = 3,600,000 Joules
for a disc type (electromechanical) meter the number of disc revolutions to indicate 1 kwh would be found by the formula 1000/ Kh, the watthour constant of the meter.
1 mwh = 1000 kwh hence 4 mwh = 4000 kwh
1 PJ equals 277 777 777.78 kWh
Roughly 1/24th or 0.04167 of one revolution.
Hi I believe it is 277.7 kWh per Gj. Cheers
A 1000 watt device operated continusouly for 1 hour would equal 1 Kwh.
0.001167 kWh/°C/l at 100% efficiency.

If you have a device of 1 KW, if this device work during an hour, this device will consume 1 KWH. If the device works during 15 min, it will consume 1KW(15 min/60 min)= 1(1/4)= .25 KWH. That is you will obtain(get?) KWH on the following way: KWH = time in hours X KW
1 Mwh = 1000 Kwr
Only 1. Which is why the same face of the moon is always towards the earth.
