![]() 1 bar = 750.062 torr (mmHg) → bar to torr.1 bar = 1000 millibars → bar to millibar.The most frequently used units of pressure are pascal (Pa), kilopascal (kPa), megapascal (MPa), psi (pound per square inch), torr (mmHg), atm (atmospheric pressure) and bar.Īn atmosphere (atm) equals to the air pressure at the sea level at a temperature of 15 Celsius.īar is a metric pressure unit and equals to 100 kilopascals which is almost equal to the atmospheric pressure. The most frequently converted pressure units: Ton force/square inch, ton force/square meter and torr (mmHg)" Newton/square meter, ounce force/square inch, pascal (Pa), pound force/square foot, psi (pound force/square inch), ton force/square foot, Megabar, megapascal (MPa), meter of air, microbar, micropascal, millibar, millimeter of mercury, millipascal, millitorr, nanobar, nanopascal, Kilogram force/square millimeter, kilobar, kilopascal (kPa), kilonewton/square centimeter, kilonewton/square meter, kilonewton/square millimeter, kip/square foot, Gigapascal, gram-force/square centimeter, hectobar, hectopascal, inch of air, inch of mercury, inch of water, kilogram force/square centimeter, kilogram force/square meter, "atmosphere (atm, standard), atmosphere (technical), attobar, attopascal, bar, barad, barye, centimeter of mercury (0☌), centimeter of water (4☌), centibar, centipascal, centipascal, centitorr, decibar,ĭecipascal, dekabar, dekapascal, dyne/square centimeter, exabar, exapascal, femtobar, femtopascal, foot of air, foot of mercury, foot of water, gigabar, However, other units like inches of mercury (inHg) and pounds per square foot (psf) are also used in specialized fields. In the Imperial system, the most popular pressure unit is the Pound per Square Inch (psi). However, the Bar (bar) is also commonly used for expressing pressure in Metric applications. In the Metric system, the Pascal (Pa) is the primary unit for pressure. Millimeter of Mercury (mmHg): Often used in medical settings for blood pressure measurements. Atmosphere (atm): A unit used to express atmospheric pressure, especially in weather reports.ĥ. Pound per Square Inch (psi): Commonly used in the United States for measuring pressure in various industries.Ĥ. Bar (bar): Widely used in meteorology, industrial processes, and fluid dynamics.ģ. Pascal (Pa): The SI unit of pressure, commonly used in scientific and engineering applications.Ģ. The converter will instantly displays the converted pressure value, rounded to four decimal places by default.ġ. Select the target pressure unit you wish to convert to.Ħ. ![]() Select the initial pressure unit you wish to convert from.Ĥ. By default, the converter is set to round the results to four decimal places.ģ. Select the desired accuracy level from the provided drop-down list. Here's a step-by-step guide on how to use the pressure converter:Ģ. If you require greater precision, you can manually adjust the number of decimal places up to 10. By default, the pressure converter rounds the result to 4 decimal places for clarity and convenience. Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types.The pressure unit converter provides quick and accurate conversions, making it a valuable tool for engineers, scientists, meteorologists and anyone dealing with pressure measurements. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. Its official symbol is "bar" the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars.Ĭonversion calculator for all types of measurement units. The word bar is of Greek origin, báros meaning weight. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. psig to kilogram-force/square millimeter.You can do the reverse unit conversion fromīar to psig, or enter any two units below: Enter two units to convert From:
