Wells & water/ CALCULATOR
Convert water pressure into metres of head and psi using a stated density.
Prepare the measurements with these instrument guides.
FROM ESTIMATE TO ACTION
For a system-pressure comparison, use gauge pressure relative to ambient air, not absolute pressure relative to vacuum. Record units, measuring point, date and whether water was flowing. This tool changes units, not the pressure reference: it does not add or subtract atmospheric pressure. Use an existing safe reading; do not loosen a pressurised connection to obtain one.
At 3 bar and 998 kg/m³, the example gives 30.65 m of pressure head and 43.51 psi. These are example inputs, not a required household pressure. With the same 3 bar but 1100 kg/m³, head falls to 27.81 m while pressure remains 43.51 psi. Use density appropriate to the fluid and temperature; changing density changes equivalent column height, not the pressure-unit conversion.
The calculation uses standard gravity 9.80665 m/s². Equivalent pressure head is not a guaranteed lifting height or total pump head at flow. Elevation differences, velocity and pipe losses need separate assessment. A static reading cannot establish residual pressure during use or locate a restriction by itself. Zero input returns zero in the same reference; negative pressure is outside this tool’s input range. Do not use the result as a pressure-rating or safety approval.
