I added the following lines to the Miscellaneous`Units` package to
convert to basic SI units.

BasicSI::usage = "BasicSI[expr] converts an expression to it's basic
SI units."

BasicSI[expr_] := expr //. $SIPrefixes //. $ToSI //. $ToFundamental

the following call resolves your problem then:
N[PowerExpand[BasicSI[Sqrt[Joule/Gram]]]]
