No measured figure exists for this shape. Copied from the Collins glass on this site, which shares its 400 ml capacity. The figure is an estimate. Crushed is taken as 7% above cubed: loose crushed ice weighs about 593 to 640 kg per cubic metre against 917 for solid ice, roughly 65% solid, where loose cubes run about 61%.
Every drink below was checked against this figure at build time. A recipe that does not fit its stated vessel fails the build rather than shipping.
