To use a simple analogy:
the amount of overflow is the displacement.Displacement is the weight of the water pushed out of the way by a warship.To be specific, definition of displacement varied depending on the time.
Before the Washington Naval Treaty, Normal Displacement included weight of the ship, fully manned, 3/4 ammunition, 1/2 miscellaneous stores, 1/4 fuel and 1/2 boiler feed water.
From after Washington Naval Treaty until the end of WW2, Standard Displacement is weight of the ship, fully manned and included all ammunition and stores.
* In Washington Naval Treaty, displacement doesn't include fuel and boiler water.
The definition is made on behalf of UK and USA who have large area to defend and thus required more fuel and fueling base. This means the ship can load more fuel without being classified as heavier ship.
