Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weigh ...
until , the four ''Batillus''-class ships were the second largest ever constructed when measuring deadweight tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provi ...

While there were minor differences between the four ''Batillus''-class ships, they all approached a gross tonnage (GT) of 275,000 and tonnage, and had a length overall of over (longer than all but a few of the tallest skyscrapers in the world).
