70.99 grams of liquid hydrogen occupies a liter of space. That's a physical constant that can be looked up, and relates to a density of 0.07099 g/mL = 0.07099 kg/L = 0.07099 mt/cumet.

The inverse of 0.07099 = 14.09 cubic meters per metric ton of L-hyd, or 14.09 cumets per dton, usually rounded to 14. (What's a 6 parts per thousand error among friends? Well, in a modern sailing ship, that's "the ship capsizes" or "the ship sinks," but we'll suspend our disbelief like good players and GMs.)

I'm assuming here that the authors said the 1.5x1.5x3 m tactical square is approximate because that's approximately one dton and not exactly one. (It is in fact FORTY-ONE parts per thousand error...but rounding it off into pseudo-5 foot squares to match the rest of the d20 system works fine.)

That clears that up perfectly, the "approximately" applies to the squares rather than the actual volume then. Not sure why I'd forgotten it was in reality 14 cubic meters (close enough so for sure). Too long a CT gearhead I guess

wow so many responces to what i thought was a simple question, is wondering if maybe i shouldnt ask no more.....

Yeah Right!!!!!
i gots to ask when i dont know, or if im confused, or just to comment about something. thanks all for the help

To put that another way, if any part of the system, be it map or specifications, gets in the way of my story, it gets cycled out the airlock without mercy. If the story demands that they can squeeze the Serpent-class scout into the Type R's cargo bay, then they can. I might make them make T/Engng rolls to unhinge the doors to get it in there or something, but it'll happen...to a point, of course. A Sulemein with its wedge design ain't going in there without a whole lot of plasma cutting... [/QB]

Too right, and the rules lawyers can go in the airlock too. Why spoil a good adventure just for the sake of the third decimal place on a rule someone pulled out of the air thirty years ago?
Rules = guidelines in my book, I tweak em all.

 

[far-trader]

Yep, I don't go to the detail of decimal points at all on deckplans (in designs 1 point rarely, never more if I can help it) and agree with the above. Though I strive for accurate depiction under the rules myself I try to be less demanding of others but...

...what really frosts me are deckplans that take extreme liberties, like 200% over stats or "decks" that are in some alternate dimension or all of 10cm high but not noted as such That'll break the story right quick too when the belief suspenders snap.

No extreme is good

I'm just saying

 

[princelian]

I use the "within 20%" (or was it 10%?) rule in the older Traveller rulesets for my deckplans. They all fall into +/- that percentage.

However, I **WAS** an evil b*st*rd to my players one campaign. I handed them the ship stats and the deckplan I'd drawn out and told them early in the time they had the ship that I'd strictly followed space allocation rules this time "just to see how hard it would be."

It was, oh, twelve or so sessions later that one of them, bored because the party was separated and I was resolving the other group's actions, actually counted up the allocations and discovered that, wait a minute! those dimensions for the power plant, jump drive, and other internal components weren't right. The total for the ship volume was right, though...

They then began searching the ship for hidden compartments, and lo and behold, that's where the extra tonnage went. And in those compartments was a treasure trove of OH!!! so illegal contraband. (They got in rather a lot of trouble over it, actually.)

They were, um, rather upset that their characters didn't get a perception roll of some kind to notice the compartments' existence, and my answer was simply "well, which one of you has the Naval Architect skill?" After that, those players made sure that at least one member of the party had a background that included NA skill.

That's very "Evil Genius(tm)" of you princelian.

Love it

 

[mike wightman]

A while back I calculated that when doing deckplans at 13.5 m^3 per ton (1.5mx3mx3m)then for every 100t of ship you get seven 1.5m squares to allocate as you like as common area, corridor etc.

I like the idea of a hidden compartment even more...

anything could be lurking inside

 

[princelian]

Or anyone...

That inexplicable power drain on the plant - not much, just some loss of voltage that's impossible to track down...

Those few cumets of missing space...

And a low berth that's the hiding place for... someone... eeeeeebil (evil). (Or someone unjustly persecuted by the gov't.; insert campaign twisting revelation here...)

No Scott, far-trader is correct.

T20 invented a unit of convenience called the "volume" or vl for short - it does not mean litre.

1 vl = 10 litres.

In the Travellers'Aids dealing with vehicles, and the vehicle catalgue, the value of 1 vl was changed to be:

1vl = 5 litres

It's a bit of a mess really.

Here I was thinking vl was just a way of distinguishing "l" from "1" from back in the old days when typewriters sometimes didn't have a separate key for the "1" ... and then thinking I was missing something in the math or overlooking a typo somewhere...

Sigh. Yet another reason to revise the whole mass-volume standard to something that makes more sense than dT(H2).

 

[mike wightman]

I think the way Star Cruiser did things for Traveller:2300 is pretty good.

m^3 for volume

metric tons for mass

MW for power

these are the units I'd use.

 

[Scott Martin]

Strangely the way I design ships IMTU.

The Republic looks at Imperial standards strangely: Why would you ever care what mass of liquid hydrogen you are displacing? (They have rumors of Imperial pleasure yachts that cruise Gas Giant Oceans to explain this oddity)

MJ is useful for penetration, and smaller pieces of equipment (stuff you'd put in a backpack for example) are best to have in units of liters and kilograms. That said, this type of equipment isn't really a "fleet" discussion...
