find the conversion factor between kilowatthour and erg using
dimensional method ???????

Ved Prakash Lakhera · Accepted Answer

1 kilowatt hour=3 6×106 J 
1J =1 Kg ms-2×m=1Kg m2 s-2
therefore   3 6×106 J=3
6×106 Kg m2 s-2 so   3
6×106 Kg m2 s-2=n g cm2 s-2
or     n=3
6×106(Kgg) mcm2 ss-2
or       n=3
6×106 1000g1g 100cm1cm2 1-2
or        n=3 6×1013
Therefore 1 Kilowatt hour = 3
6×1013 erg
