Pressure unit converter
In the field of pressure measurement is used except
basic SI unit of pressure - Pascal, many others. Their conversion is not always trivial and therefore company
CRESSTO s.r.o. offers this tool as a
pressure units converter.
Pressure units
Pascal
[ Pa ] = N/ m² Basic
pressure unit in SI.
Hectopascal
[ hPa ] = 100 Pa = 100N/ m². is a 100 multiple of basic
pressure unit Pascal. Hectopascal is usually used in meteorology.
Bar
[ Bar ] = 100 000 Pa. The secondary unit of
pressure in SI. The bar is used in industry because approximately corresponds to older
pressure unit of one atmosphere.
Atmosphere
[ Atm ] = kg/cm2 = 98066 Pa. It is obsolete
unit of pressure, not belonging to the system of SI units. This unit is sometimes called a
technical atmosphere. In addition, exist unit called
physical atmosphere, which is equal to the normal barometric pressure at sea level, ie 101 325 Pa.
Kilogram per square centimeter
[ kg/cm² ] see Atmosphere
Millimeter of water column
[ mmH2O ] = 9,8066 Pa. This unit is derived from the practical measurement of very low pressure through the water filled U tubes. mmH2O is still using particularly in the aircondition or in combustion process. We can also meet with the same defined entity, but 1000 times larger - mH2O.
Inch of water column
[ InH2O ] = 249,1Pa. Similar to previous unit, still widely used in Anglo-American countries.
Torr
[ torr ] = mmHg = 133,32 Pa.
Outdated, not allowed unit of pressure. Derived from the physical implementation of mercury manometers. This unit was used especially in meteorology, where was replaced similar unit - hPa (hectopascal).
Millimeter of mercury column
[ mmHg ] see Torr. This unit is still used primarily in medicine.
Inch of Mercury column
[ InHg ] = 3386,4 Pa. - Similar to the previous unit, used in Anglo-American countries.
Pound per square inch
[ PSI ] = 6894,8 Pa - The most commonly used unit for measuring
pressure in Anglo-American countries.
Pound per square foot
[ PSF ] = 47,881 Pa - Rarely used unit for measuring low pressures.
