Head to Pressure Calculator
To convert head (height) into pressure, multiply the height by 0.433 and the specific gravity of the liquid.
In fluid mechanics and hydraulics, understanding the relationship between head and pressure is crucial. The head to pressure calculator helps convert fluid column height (head) into pressure based on the liquid’s specific gravity (SG). This is commonly used in pumps, pipelines, and hydraulic systems to determine how much pressure a given height of liquid will generate. Whether you’re calculating pump head pressure, static head pressure, or pressure in psi, bar, or kPa, this conversion is essential in designing efficient fluid transport systems.

| Symbol | Meaning |
|---|---|
| P | Pressure (psi) |
| H | Head Height (feet) |
| SG | Specific Gravity of the Liquid |
What is Head to Pressure?
Head to pressure refers to the conversion of fluid column height into pressure. In hydraulics and pumping systems, “head” represents the height a liquid is lifted, while “pressure” refers to the force exerted by the liquid due to gravity. This relationship is important in pump design, pipe flow analysis, and water distribution systems.
For example, 1 meter of water head generates approximately 0.098 bar (or 9.81 kPa) of pressure. Similarly, in pump systems, knowing the head-to-pressure conversion helps in selecting the right pump for desired pressure output.
Whether you’re working with differential pressure, static head pressure, or head loss in pipelines, understanding this concept ensures efficient fluid movement.
Final Words:
Finally, converting head to pressure is essential in hydraulic, industrial, and engineering applications. Whether you’re dealing with pump head pressure, feet-to-bar conversion, or static pressure calculations, this formula helps determine the exact pressure exerted by a fluid column.
