Head to Pressure Converter
Convert a liquid column height into static pressure for any specific gravity.
Every 10 m of water adds almost exactly 1 bar (98 kPa). Tank-bottom design pressure is just this plus any vapour-space pressure.
Formula
Head to Pressure Converter is a free head to pressure for process, mechanical and water engineers โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Head to Pressure Converter

Frequently asked questions
What formula does the Head to Pressure Converter use?+
It computes P = ฯยทgยทh, per Hydraulic Institute โ pump terminology. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Every 10 m of water adds almost exactly 1 bar (98 kPa). Tank-bottom design pressure is just this plus any vapour-space pressure.
Does this work for any fluid?+
Yes โ density and viscosity are inputs (with common fluids suggested in the field hints), so the same physics applies to water, oils, gases and process fluids. Compute always runs in SI internally, so unit mix-ups can't corrupt the result.
Is the Head to Pressure Converter free to use?+
Yes โ completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
