How to calculate dTons of a ship?

[JRoss]

So I'm working on a ship concept, and I've got its physical dimensions down, but I want to know how many tons to give it for creating it stats. It's a rocket with a diameter of 28 meters and a length of 78 meters. The engine takes up the back 33.5 meters, which leaves the 44.5 meters for the mission module. That module has an internal volume of 11,325 meters. Can anyone tell me how I should calculate the dTons of this baby?

In Mongoose Trav it is 14 cubic meters to the dton. So figure your M3 and divide by 14.

Thanks, F33D. That gives this ship a dTon value of 1545 once you account for empty space.

You should round up to an even 1600 Dtons because of the way the tables work and don't support the odd tonnages. All your machinery calculations are going to be based on 1600 anyways so you might as well utilize that space for something.

Okey-dokey.
