Nah, you need to match crossectional area to use the same length. A square port with the same diameter as a round one needs to be longer to get the same tuning frquency because it has more area.

Don't look at volume. A really "wide" port can have the same volume as a "skinnier", longer one, but will tune much differently.

Length and crossection is what you need to worry about matching.
