![]() ![]() Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. One PSI is equal to 2.31 Feet of Water and that means we can also write it as 1 PSI 2.31 Feet of Water, feel free to use our online PSI to Feet of Water. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.Ĭonversion calculator for all types of measurement units. It is assumed that the pressure value is the difference in pressure between the measurement point and the top of the fluid. Enter the pressure reading measured at the base of the fluid column. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. 1 psf (lb f /ft 2) 47.88 N/m 2 (Pa) 0. 0 Density of fresh water (1000 kgm-3 4C) SG Specific gravity of liquid (e.g. This calculator uses the js-quantities library by gentooboontoo for unit conversions. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. P g h The calculator uses the following values for these parameters: f r e s h 997.0474 k g / m 3 (for freshwater) s a l t 1023.6 k g / m 3 (for saltwater) g 9.80665 m / s 2 Learn More For watertight enclosure design, please check out Under Pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.You can do the reverse unit conversion fromįeet of water to psig, or enter any two units below: Enter two units to convert From: If the test and balance technician uses the correct multiplier from the glycol table above, the multiplier would be 2.18. This would indicate we are flowing 950 GPM or 5 below the design flow rate. 1 psi in water column millimeter is equal to: 703.07: 1 psi in newton/square centimeter is equal to: 0.68947572927646: 1 psi in ksi is equal to. 40 PSI x 2.31 multiplier 92.4 ft of head. 1 psi in feet of water is equal to: 2.31: 1 psi in gigabar is equal to: 6.8947572927646e-11: 1 psi in gigapascal is equal to. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Assume the pump differential pressure was 40 PSI. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭonversion calculator for all types of measurement units. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. A pressure of 1 Pa is small, therefore everyday pressures are. One pascal is defined as one newton per square meter. For technical drawings and 3-D models, click on a part number. The SI unit of pressure is the pascal (Pa). They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications. ![]() would exert a maximum hydrostatic head pressure of 20 feet of water column. Psi to Water Column, or enter any two units below: Enter two units to convert From: Keep tabs on liquid levels in pump and tank applications with these gauges a dual scale displays pressure in feet of H2O and psi. 1 inch of water column 0.03613 PSI (27.678 inches of water column 1 PSI). You can do the reverse unit conversion from ![]()
