The bar is a metric unit of pressure defined as 100,000 ... 14.503774 psi; ... Centimetre or millimetre of water; Conversion of units § Pressure or mechanical stress;
Millimetre of water (US spelling millimeter of water) [3] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 mm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 mmH 2 O (4 °C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 mm = 9.8063754138 Pa ≈ 9.80638 Pa, but conventionally a nominal maximum water ...
A msw is defined as 0.1 bar (= 10,000 Pa), is not the same as a linear metre of depth. 33.066 fsw = 1 atm [citation needed] (1 atm = 101,325 Pa / 33.066 = 3,064.326 Pa). The pressure conversion from msw to fsw is different from the length conversion: 10 msw = 32.6336 fsw, while 10 m = 32.8083 ft. [citation needed]

Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of 100 kPa (1 bar). Conversions between each volume flow metric are calculated using the following formulas: Prior to 1982,
The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in 2). ksi are not widely used for gas pressures. They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. [4] The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa ...
The metre (or meter) sea water (msw) is a metric unit of pressure used in underwater diving.It is defined as one tenth of a bar. [1] [2]The unit used in the US is the foot sea water (fsw), based on standard gravity and a sea-water density of 64 lb/ft 3.
SG is the specific gravity of the fluid (for water = 1), Δ P is the pressure drop across the valve (expressed in psi). In more practical terms, the flow coefficient C v is the volume (in US gallons) of water at 60 °F (16 °C) that will flow per minute through a valve with a pressure drop of 1 psi (6.9 kPa) across the valve.
