Displacement Ton

With respect to Deckplans and Life Support, most people calculate volume as 1 ton per 2 squares (with each square representing 1.5 x 1.5 x 3 meters = 6.75 cubic meters and 2 squares = 13.5 meters). However, if 1 ton is actually 14 cubic meters, then 3.5% of the space is missing which is plenty for air scrubbers and water filters.
They probably should be shown on Deckplans, but they may not have been completely ignored, just dropped in the name of simple playability.

I wonder why they didn't just say that one square of 2.4 x 2.4 (x 2.4 high) m = 1 dt for the deckplans? In fact this also has the advantage (for those who favour imperial measurements) of being exactly an 8ft x 8ft x 8ft volume.
Or that eight squares of 1.2 x 1.2 (x 1.2 high m) arranged as a 2x2x2 grid = 1 dt (1.2³ = 1.728 = 14 divided by 8)? It'd be easier to draw the deckplans then wouldn't it? And in terms of area taken up on a deckplan, one person would easily fill up one of those 'eighth' squares (and take up two of the vertical axis of the 2x2x2 grid if considering height too) - in fact if I stand up with my arms outstretched from my sides at 90 degrees to my body, that's a span of about 4ft. And it so happens that one of these 'eighth' squares would be a 4ft x 4ft x 4ft volume too.

Exactly - the original Traveller deckplans were designed so that you could play skirmish wargames of boarding engagements or what-have-you (Using the 'Snapshot' or 'Azhanti High Lightning' rules). A 5'/1.5m square was considered the size to fit a single person, while still giving them enough room to dodge, fall prone, or move around.
One dton is shown by two 1.5m squares, which means the distance between decks is 3.111m. In practical terms, that means a ceiling height of 2.5m and then 611mm of between-decks space in which you fit your life support, grav plates, plumbing and wiring conduits.

Regarding deck height. For military and Scout ships, it wouldn't surprise me if the deck heights weren't lower.
On the submarine I served on, the average deck height was rarely more than 2 meters (I have scars on my head to prove it).
I am NOT advocating changing the scales here, I just wanted to point out that not every ship, from every polity in every Traveller Universe will have the same deck heights.
Didn't Hiver ships actually go with 1.5m heights and use 4 squares for deck space?

Only if no other race will be serving on such a ship. While we aren't informed about the size of the Hive Federation's primary bureaucrats (the Gurvin) the obligatory warrior race (the Ithklur) is tall enough to call for standard deck seperation.

Hivers are only 1.5 meters tall.
So hiver starship decks will generally be a little taller than themselves.
Also, hivers usually get around on some kind of grav vehicle,
which would indicate deck height at the normal height of 2.25 out of 3.0m
the remaining space is taken up by ducting and pipes, access crawlways
and ofcourse the next deck above.
