if we convert ampers into kwh or mwh ,which one formula use
by us,pls tell me?

Answer Posted / omar aziz

Look , Always try to understand what quantities you have
and their significance. This will help you derive other
quantities yourself using the first principles. Lets derive
KWhr from current I !

Firstly you need to know the voltage at which this current
is drawn from its supply. V

Once you have this info you can find the power flow = V x I
this is in W if you use SI units throughout

Divide it by 1000 to get KW

KWh = unit of energy therfore its Power x time

Now how long would your current be drawn for. say its a fan
drawing 2 Amps and you keep it on for 5 hrs at 240V

(240V x 2A x 5hr)/1000 = 2.4 KWhr
