Static Pressure Calculator
Compute pressure from fluid column height or column height from pressure
Pressure calculator is mobile-device-friendly as of February 12, 2015
Units in pressure calculator: atm=atmosphere, C=Celsius, cm=centimeter, F=Fahrenheit, ft=foot, g=gram, in=inch, kg=kilogram, km=kilometer, lb=pound, m=meter, mbar=millibar, mm=millimeter, M=Mega, N=Newton, Pa=Pascal
Pressure equation: P = ρgh
where P = pressure (N/m2), ρ = mass density of fluid (kg/m3),
g = acceleration due to gravity = 9.8066 m/s2, h = height of fluid column (m)
Density must be entered as a positive number. Height and pressure can be entered as negative numbers. The calculator does not check for unrealistic heights or pressures, such as pressure below that of a complete vacuum.
