Meters of head to pounds per square inch
Type a value in m to get it in psi instantly.
That's 1.5× as high as a house supply, while a town mains is 1.33× higher. That would reach about 10 floors up a building.
Convert the other way: psi to m
What it means
How high will it push?
This is static head. A real system also loses head to friction in the pipe, which grows with the square of the flow.
The math
How to convert m to psi
A column of fluid pushes with p = ρ g h: the height times the density times gravity. For water that is about 1 bar every 10 meters, or 1 psi every 2.31 feet. The figures below use the fluid selected above.
Example: 30 m = 42.5932 psi.
The table below is for Water (998 kg/m³).
