The Effect of Density on Measurement Units

[CmonAlready]

This admittedly may be the absolute most stupid question in recorded history: The plastic cap cup that comes on the top of a NyQuil/DayQuil bottle measures up to 30 ml. Is that 30 ml specific to said products due to density or would filling it to the 30 ml line with water, in fact, be 30 ml of water as well?

mL is a unit of volume, which is the amount of physical space matter occupies, regardless of its density. So if you fill that cup with water up to the top line, it'll indeed be 30mL of water.
