Pressure Head Converter
Convert fluid pressure to pressure head and back using fluid density and gravitational acceleration.
How to Use the Pressure Head Converter
Enter a pressure value to convert it into an equivalent fluid head using the relationship between pressure, density and gravity.
Practical Example
For water near standard conditions, about 9.81 kPa corresponds to roughly 1 meter of water head.
Factors That Affect the Result
Fluid density, temperature, local gravity and whether pressure is gauge or absolute can affect the physical head represented by a pressure value.
Frequently Asked Questions
What is pressure head?
It is the height of a fluid column equivalent to a given pressure.
Does fluid density matter?
Yes. Denser fluids require less height for the same pressure.
Is 1 meter of water exactly 9.81 kPa?
It is approximately that value under standard assumptions.
Formula and Practical Context
Pressure head relates pressure to fluid density and gravity through h = P/(ρg). A fixed pressure therefore corresponds to different head for fluids with different density, and water-head conversions should state the assumed density and gravitational acceleration.
