Pump head converter
Convert head in meters into the pressure it actually produces. Pick the fluid first: a column of oil pushes less hard than a column of water.
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.
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.

Three things worth knowing
-
10 meters of water ≈ 1 bar
More precisely 0.98 bar, or 14.2 psi. Every 2.31 feet of water column is 1 psi, which is the version US plumbers carry in their heads.
-
Why pumps are rated in height
A centrifugal pump gives the same head whatever the liquid, because the impeller throws every fluid to the same speed. Rating it in pressure would need a different number for each one.
-
Head is not pressure
30 m of mercury is 40 bar; 30 m of gasoline is 2.2 bar. Same head, eighteen times the pressure, because the fluid is what fills the column.

Background
About head
Pumps are rated in meters of head, not in pressure, because head is the same whatever is in the pipe: a pump that lifts water 30 m lifts diesel 30 m too. The pressure differs, because diesel is lighter.
The link is p = ρ g h, and for water that works out at roughly 1 bar per 10 meters.
