Convert 1erg into joule with dimensional formula
Answers
Answered by

SI unit of energy or workdone is Joule
and CGS unit is erg.
work is a force acting on a unit distance
therefore,
dimensional formula of work = [ M1 L2 T-2 ]
so n2 = n1 (M1/M2)^1 (L1/L2)^2 (T1/T2)^-2
= (1Kg/gm)^1 (1m/1cm)^2 (1sec/1sec)^-2
= (1000/1)^1 (100/1)^2 (1/1)^-2
= 1000 x 10000 x 1
= 10^7
so 1 joule = 10^7 erg
i hope it will help you
