How do you convert Hg to kPa?
A pressure measured in millimetres of mercury can be converted to a kilopascals reading using the following conversion factor calculation:
- 1 kPa = 1000 pascals (Pa)
- 1 mmHg = 133.322 pascals (Pa)
- kPa value x 1000 Pa = mmHg value x 133.322 Pa.
- kPa value = mmHg value x 0.133322.
Is PSI same as HG?
In older literature, an “inch of mercury” is based on the height of a column of mercury at 60 °F (15.6 °C). In Imperial units: 1 inHg60 °F = 0.489 771 psi, or 2.041 771 inHg60 °F = 1 psi….

Is psia and PSI the same?
PSI stands for pounds per square inch, and it’s the measure of air force delivered by the air compressors. For example, a compressor could be rated at 125 psi, which means that it delivers 125 pounds of pressure per square inch. PSIA. PSIA is pounds per square inch absolute.
Is kPa and mmHg the same?
KPa stands for kilopascal and describes the pressure exerted on a surface. KPa is widely used internationally as a unit of pressure and also measures eg the tyre pressure of cars. The unit mmHg (millimeter mercury column) is also used to measure blood pressure.
How do you convert psig to psia?
Note that PSIG is always lower than PSIA. The formulas to describe the relationship are: PSIG + 1 atm = PSIA and PSIA – 1 atm = PSIG (where atm is atmospheric pressure). It is easy to calculate PSIA or PSIG or convert between the two.
What does Hg mean in pressure?
Inches of Mercury
(or in Hg) Unit of atmospheric pressure used in the United States. The name comes from the use of mercurial barometers which equate the height of a column of mercury with air pressure. One inch of mercury is equivalent to 33.86 millibars or 25.40 millimeters. See barometric pressure.
Is PSI the same as kPa?
psi (pounds per square inch) is the standard tire pressure measurement used in the USA. kPa (Kilopascal) is a unit of measure in Europe and other areas that use the metric system. BAR is a unit of measure in Europe and other areas that use the metric system and it is defined as 100 Kilopascals.
