Translations of this page?:

The pressure caused by the weight of an equivalent column of liquid upon a unit area expressed by the height or distance of the liquid above the point at which the pressure is measured. Although head refers to distance or height, it is used to express the pressure resulting from the weight of a body of liquid since the weight is directly proportional to the height.
