Pressure is the force exerted per unit area and there are different forms of pressure such as: B. uniform and different pressure, etc. This article explains pressure units. Various types of standard, common, and uncommon units for measuring pressure are explained in detail.
Pascal (Pa):
The pascal, the SI unit of pressure, defines pressure as one newton per square meter. It serves as the basis for pressure measurements in the International System of Units.
Atmosphere (atm):
Standard atmospheric pressure at sea level is given as 1 atmosphere and is used as a reference for pressure comparisons.
Millimeters of mercury (mmHg):
Commonly used in barometers, mmHg represents the height of a column of mercury in millimeters, providing an accurate measurement of air pressure.
Inch of mercury (inHg):
Similar to mmHg but measured in inches, inHg is commonly used in the United States, particularly in a meteorological context.
Bar (Bar):
One bar equals 100,000 Pascals and is a versatile unit used in meteorology, engineering and various scientific applications.
Millibars (ambar):
mbar, one thousandth of a bar, is often used in weather forecasts and is a convenient unit of measurement for air pressure.
Torr (Torr):
A torr is approximately 1/760 of an atmosphere and is an alternative unit of pressure, particularly in scientific research.
Pound Force per Square Inch (psi):
Commonly used in engineering and fluid dynamics, the PSI measurement measures pressure by the amount of force exerted per square inch.
Pound force per square foot (psf):
In engineering, psf is used to measure pressure on surfaces and quantify the force applied per square meter.
Kilogram force per square meter (kgf/m²):
The pressure that one kilogram of force exerts on one square meter of area.
Newton per square millimeter (N/mm²):
Units commonly used in engineering to indicate high pressures on small scales.
Megapascal (MPa):
Used primarily to indicate greater pressures in materials science and engineering.
Kilopound force per square inch (ksi):
It is often used in material testing and indicates high strength of materials.
Dyn per square centimeter (dyn/cm²):
Used in scientific and engineering applications and is a unit of the CGS system.
Millipascals (mPa):
Used to establish low pressure measurements in precise scientific experiments.
Kilogram force per square centimeter (kgf/cm²):
Metric unit applicable in certain technical contexts.
Inches of water (inH₂O):
Used to represent the pressure exerted on the surface and often used to measure water levels.
Feet of water column (ftH₂O):
Used as an alternative measure in fluid dynamics.
Pounds per square foot (pdl/ft²):
This is a unit of the FPS system and is used to measure specific scientific contexts.
Technical atmosphere (in):
This unit is used in specific technical scenarios.
Understanding these pressure units provides a comprehensive overview of the different ways to measure pressure. From the commonly used Pascal unit to specialized units for specific applications, each unit plays a critical role in quantifying pressure in various fields such as meteorology, engineering, and scientific research.
