Static Pressure Calculator 
Compute pressure from fluid column height or column height from pressure 

Pressure calculator is mobiledevicefriendly 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/m^{2}), ρ = mass density of fluid (kg/m^{3}),
g = acceleration due to gravity = 9.8066 m/s^{2}, h = height of fluid column (m) Introduction 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. References Mays, L. W. editor. 1999. Hydraulic design handbook.
