Hydraulic head, abbreviated as h, is the measurement mechanical energy due to pressure of a fluid from a higher elevation to a lower elevation. It is measured in feet or meters of water. This calculation converts pounds per square inch or Pascal into feet or meters of head.

$$\large{ h = \frac {p}{g \; \rho} }$$
Symbol English Metric
$$\large{ h }$$= head $$\large{ ft }$$ $$\large{ m }$$
$$\large{ \rho }$$  (Greek symbol rho) = density $$\large{\frac{lbm}{ft^3}}$$ $$\large{\frac{kg}{m^3}}$$
$$\large{ g }$$ = gravitational acceleration  $$\large{\frac{ft}{sec^2}}$$   $$\large{\frac{m}{s^2}}$$
$$\large{ p }$$ = pressure $$\large{\frac{lbf}{in^2}}$$  $$\large{\frac{N}{m^2}}$$
