There is no mathematical conversion needed - 1 psi is equal to 1 psi. The terms "psig" and "psi" are often used interchangeably to refer to pounds per square inch of pressure. However, "psig" specifically denotes pressure relative to the local atmospheric pressure, while "psi" is an absolute measure.
1 bar is equal to 100 Kpa. Therefore, 0.5 bar is equal to 50 Kpa.
One pound per square inch (psi) is equal to approximately 2.31 feet of water. This means that a column of water that is 2.31 feet tall exerts a pressure of 1 psi at its base.
1 kilonewton is equal to 1000 newton.
1 kg/sq cm = 14.2233 psi 140 kg.sq cm = 140 x 14.2233 psi = 1991.262 psi
1 kilonewton is equal to approximately 0.145 pounds per square inch (PSI).
1 psig is equivalent to 51.71 mm (2 in) of mercury or to approx 700 mm (27.5 in) of water. Technically one cannot have apsig. Psig represents a pressure reading of the pressure above normal atmospheric pressure of 14.7 psi. You mean a psi.
1 bar is equal to 100 Kpa. Therefore, 0.5 bar is equal to 50 Kpa.
"1 psi is equal to how much kgf/cm2?" since, 14.696 psi is equal to 1.033 kgf/cm2 so 1 psi = 0.070291 kgf/cm2
1 bar = 14.5 psig so 3.5 bar = 51 psig (what your significate figures)
Pound per Square Inch = PSI means 1pound in terms of pressure will be 1 psi.
Psig (pound-force per square inch gauge) is a unit of pressure relative to atmospheric pressure at sea level. By contrast, psia measures pressure relative to a vacuum (such as that in space). Most pressure gauges, such as tire gauges, are calibrated to read zero at sea level, because most applications require the difference of pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.695948804 psi. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.695948804 psi. Thus a reading of 30 psig on a tire gauge, represents an absolute pressure of 44.695948804 psi.
1 Torr is equal to approximately 0.0193367 psi.
One pound per square inch (psi) is equal to approximately 2.31 feet of water. This means that a column of water that is 2.31 feet tall exerts a pressure of 1 psi at its base.
1 kilonewton is equal to 1000 newton.
(psi x 6.89476 = kPa). So, 70 psi x 6.89476 = 482.633 kPa
1 BAR = 100kPa = 14.5038 PSI
1 ksi is equal to 1,000 psi
