Answer:

#"Specific gravity"=rho_"substance"/rho_"reference substance"#

Explanation:

And the #"reference substance"# is typically water, for which under standard conditions, #rho_"water"=1*g*mL^-1#, or #1*g*cm^-3#.

And thus the product #rho_"water"xx"specific gravity"=rho_"substance"# #=# #0.67*g*cm^-3#.
