Degrees Baume is a measure of specific gravity originally based
on assigning 10% NaCl solution a value of 10.

In the USA the relationship at 60/60 degF is usually expressed:

sp.gr. = 145/(145-Baume)

In the present case there is something wrong because 20% HCl is
nowhere near 32 Baume. What you probably have is 32% HCl, which
corresponds to about 20 degrees Baume.

Be aware that there are a bunch of other methods for reaching 
values for Baume so your milage may vary a little in Washington
DC, Amsterdam and Germany.
