Pressure Converter

Our Pressure Converter is online conversion calculator that allows you to convert units of pressure between various measurement systems. You can easily convert pascal to kilo,hecto,megapascals, millimeters of mercury to inches of mercury, bars to torrs. You can compare standard atmosphere vs technical atmosphere, inHg vs mmHg. Additionaly, you can quickly access normal blood pressure in inHg, mmHg or in Newtons per square millimeter, Mariana Trench water pressure in Pa, Mt. Everest atmospheric pressure in inHg, and so on.

Pascal [1 Pa=N/m2] Hectopascal [hPa] Kilopascal [kPa] Megapascal [MPa] Bar [bar] Newton per square millimetr [1 N/mm2] Kilogram per square meter [1 KG/m2] Technical atmosphere [at] Standard atmosphere [atm] Torr [Tr] Millimeters of Mercury [mmHg] Inches of Mercury [inHg] Psi (pound-force per square inch) [lbf/in2]
Diastolic Blood Pressure
Optimal arterial, diastolic ( phase when the heart fills with blood ) blood pressure called 'gold standard' is 80 mmHg (millimeters of mercury) or 3.15 inHg (inches of mercury)
Note, diastolic pressure between 70-90 mmHg should be considered as 'normal'.
Systolic Blood Pressure
Optimal arterial, systolic ( contraction of heart chambers, driving blood out of the chambers ) blood pressure called 'gold standard' is 120 mmHg (millimeters of mercury) or 4.72 inHg (inches of mercury)
Note, systolic pressure between 110-140 mmHg should be considered as 'normal'.
Standard Pressure
In 1999, the International Union of Pure and Applied Chemistry (IUPAC) recommended that for the purposes of specifying the physical properties of substances, "the standard pressure" should be defined as precisely 100 kPa
Mean Sea Level Pressure
Mean sea level pressure (MSLP or QFF) is the pressure at sea level. Average sea-level pressure is 1 standard atmosphere [atm], 101.325 kilopascals [kPa], 760 millimeters of mercury [mmHg] or 29.921 inches of mercury [inHg]
Atmospheric pressure on Mount Everest
Average atmospheric pressure on Mount Everest (highest mountain on the Earth - 8,848 meters above sea level) is about 3.5 times less than at sea level and it equals 280hPa.
Mariana Trench Pressure
The Mariana Trench (Mariana's Trench) is the deepest part of the oceans, and the deepest location on the Earth. Its depth is about 11km (6.8mi). (Latest reserches indicated a depth 10,916 meters (35,813 ft)).
Water pressure is over 1000 times the standard atmospheric pressure at sea level and it is about 108.6 MPa (megapascal).
Fundamental unit of pressure in the International System Of Units (SI) is Pascal [Pa]
1 Pa = 1 N / m2 (1 Newton per 1 square meter)
