We all know that standard displacement is not an absolute way of measuring displacement in ships, like using metric tonnes or long tons. 1000 tonnes equals 1102 short tons and 984 long tons always. But 1000 t standard displacement will weigh less or more tonnes depending on the ship’s class. We all know why and I would say it’s understandable: if you are going to enter into an arms limitation treaty and you have a requirement for long range ships, you want to make sure that nations that only need short range ships do not have an unfair advantage and are capable of building better ships than you as you would have to use some normal displacement to allow long range, while they could use it to add more armour, for example. So using standard displacement is a way to avoid this. But it’s rather obscure if you want to know the true displacement of a ship.
Anyway, 10,000 t (standard) ships from different classes will have different displacement if measured in the more traditional “normal displacement”, in tonnes, long tons or whatever.
And of course we have a second problem: cheating. Some countries were declaring 10,000 t standard but even if following that way of measuring their displacements, they were well above 10,000 t standard.
So my question is : is there any data source, or does anybody know what are the light and normal displacement, particularly of the 10,000 t Washington cruisers measured not in standard t but on tonnes or long tons?
Normal displacement wasn’t always measured exactly the same everywhere but I think it was close enough.
Maybe knowing the light displacement could be also very useful to better compare how displacement varied from class to class.
I'm sorry if this has been dealt with previously, something very provable, but I couldn't find it.
