Meter of Head Unit | All you need to know

The meter of head (symbol:m head) is a non-SI unit of pressure that represents the pressure generated by a one-meter column of water under standard gravity. It is widely used in hydraulics, water supply systems, pumps, irrigation, and fluid engineering to describe pressure and pump performance. Although the pascal is the SI unit of pressure, the meter of head remains popular because it directly relates pressure to water height. It is based on the principles of hydraulic head.

One meter of head is equal to 9,806.65 pascals, 9.80665 kilopascals, 0.0980665 bar, 1.42233 pounds per square inch, and 3.28084 feet of water. The meter of head is commonly used to specify pump capacity and water system pressure.
