What is the unit of measure for head in pump calculations?

Explanation:
Head is the height of a column of water that the pump can raise, so it represents energy in terms of height. That means the unit is a length measurement. In US practice, pump head is commonly expressed as feet of head, while in metric contexts you’d use meters of head. Among the options, gallons is a volume, pounds per square inch is pressure, and meters is a length unit but the typical convention in this context is feet. So the correct unit is feet.
