Pressure Units Introduction
Pascal (Pa) represents the force in newtons per square meter. Specifically, 1 pascal equals 1 newton per square meter (1 Pa = 1 N/m²). Pascals are commonly used to describe pressure in fluid mechanics, material science, and meteorology. For example, atmospheric pressure is approximately 101,325 pascals.
Kilopascal (kPa) represents 1,000 pascals. Specifically, 1 kilopascal equals 1,000 pascals (1 kPa = 1,000 Pa). Kilopascals are commonly used to describe medium-range pressures, such as tire pressure and building structural pressure.
Megapascal (MPa) represents 1 million pascals. Specifically, 1 megapascal equals 1 million pascals (1 MPa = 1,000,000 Pa). Megapascals are commonly used to describe very high pressures, such as those in industrial equipment and material testing.
Hectopascal (hPa) represents 100 pascals. Specifically, 1 hectopascal equals 100 pascals (1 hPa = 100 Pa). Hectopascals are commonly used in meteorology to describe atmospheric pressure, for example, standard atmospheric pressure is about 1013.25 hectopascals.
Millibar (mbar) represents 100 pascals. Specifically, 1 millibar equals 100 pascals (1 mbar = 100 Pa). Millibars are commonly used in meteorology to describe atmospheric pressure, such as barometer readings. Standard atmospheric pressure is approximately 1,013.25 millibars.
Bar (bar) represents 100,000 pascals. Specifically, 1 bar equals 100,000 pascals (1 bar = 100,000 Pa). Bars are commonly used to describe pressure in gas and hydraulic systems, such as the pressure in diving cylinders and atmospheric pressure in meteorology.
Torr (torr) represents 1 millimeter of mercury. Specifically, 1 torr is approximately equal to 133.322 pascals (1 torr ≈ 133.322 Pa). Torrs are commonly used to describe pressure in vacuum systems, such as low-pressure environments in laboratories.
Meters of Water Column (mH₂O) represents the height in meters of a column of water. Specifically, 1 meter of water column is approximately equal to 9,806.65 pascals (1 mH₂O ≈ 9,806.65 Pa). It is commonly used to describe liquid pressure and pressure in water systems.
Millimeters of Mercury (mmHg) represents the height in millimeters of a column of mercury. Specifically, 1 millimeter of mercury is approximately equal to 133.322 pascals (1 mmHg ≈ 133.322 Pa). It is commonly used in barometer readings and in meteorology to describe atmospheric pressure.
The pound per square inch (psi) represents pounds of force per square inch. Specifically, 1 psi is approximately equal to 6,894.76 pascals (1 psi ≈ 6,894.76 Pa). It is commonly used to describe tire pressure, hydraulic systems, and industrial equipment pressure.
The kilopound per square inch (ksi) represents thousands of pounds of force per square inch. Specifically, 1 ksi is approximately equal to 6,894,760 pascals (1 ksi ≈ 6,894,760 Pa). It is commonly used to describe material strength and high pressures in structural engineering.
Inches of Mercury (inHg) represents inches of mercury column height. Specifically, 1 inch of mercury is approximately equal to 3,386.39 pascals (1 inHg ≈ 3,386.39 Pa). It is commonly used in meteorology and aviation to describe atmospheric pressure, such as barometer readings.
