Only under certain specific circumstances. SG is a measure of _total_
solutes in a solution (both fermentable and non-fermentable). Even
suspended solids can have an effect on SG readings. OTOH - BRIX
is only the _fermentable_ portion of that total. Thus, when
non-fermentables
are influencing our SG readings, these readings must be "interpreted" in
order to derive the BRIX information.

It's not a matter of one or the other. SG is used to determine BRIX.
Thereafter, all calculations are based on the BRIX information. HTH
