HA! Traveller! I should have realised! - or remembered.

Fortunately I've included the volume in cubic metres too so you can calculate it any way you want

Funny... I'v always only played CT... and I only use 13.5m3.

You know, 1.5m X 3m (2-1.5m squares) X 3m = 13.5m3.

 

[Scarecrow]

Yeah, same here. I think in Classic Trav, whilst the actual displacement of a single dTon is given as 13.5 - they say in the rulebook to round it up to 14 to make it easier.

The difference is only a few %.

How does that compare with the volume of 1 metric ton (1,000 kg) of liquid hydrogen? [an alternate "definition" of the starship 'Ton' from CT]

At what temperature and pressure?

At what temperature and pressure?

Presumably, the Temp and Pressure that makes it around 14 cubic meters.

It doesn't matter, the density hardly changes between freezing and critical point. SG at 1atm BP 20°K is 0.0710 = 14.08m³/ton.

This suggests that 1 dTon = 14 cubic meters was "accurate" and the 13.5 cubic meters (1.5m x 3m x 3m) from the deckplans was "approximate" - not the other way around.

 

[aramis]

At higher temps, it can be larger... MUCH larger, at 1Atm.

But yeah, 14 is much better than 13.5...
