Electric Meters usually measure in KWH units. KWH is acronym for Kilo Watt Hour. It's basically units of Work/Energy. You can do the math for the Kilo Watt Hour. It's simple.

#KWH = 1000* 60*60# Watt-Sec
#rArr KWH = 3.6*10^6 #Watt-Sec

We know that, Power = (Work)/(Time)
Units of Power are Watt, Work are Joules and Time are Seconds. So, Watt-Sec is nothing but Joules.

So, #KWH=3.6#Mega Joules

One KWH is often referred to as one unit in electrical meters.
