Also, explore tools to convert newton/square meter or bar to other pressure units or learn more about pressure conversions. The newton/square meter to bar conversion table and conversion steps are also listed. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Instant free online tool for newton/square meter to bar conversion or vice versa. So a typical US 100 cubic foot tank to an Aussie would be a 12 Litre tank that has been filled to a pressure of 236 bar (3420 psi) and thus contains 100 cubic. Therefore, a pressure of 100 psi is equivalent to 6.89475729 bar. So, using the formula: Converted pressure (original pressure) x (conversion factor) Converted pressure (in bar) 100 psi x 0.0689475729 6.89475729 bar. 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.Ĭ provides an online conversion calculator for all types of measurement units. The conversion factor between psi and bar is 0.0689475729. 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). Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. lbs/square in to kilopond/square millimeter.Kilopascal to Psi Conversion Table Kilopascal ġ5 kPa = 15 × 0.1450377377 psi = 2.You can do the reverse unit conversion fromīar to lbs/square in, or enter any two units below: Enter two units to convert From: Although the pascal is more widely used in scientific contexts, psi is more often used in everyday contexts, particularly in countries like the United States as well as others under the US customary or imperial systems of units. As such, the prototype pound at the time was known as the avoirdupois wool pound.Ĭurrent use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. The system is believed to have come into use in England around 1300 and was used in the international wool trade. It is based on the avoirdupois system, a system that uses weights in terms of the avoirdupois pound, which was standardized in 1959. History/origin: Pound-force per square inch is a unit that originated in the imperial and US customary systems of units. One psi is approximately 6,895 pascals (N/m 2). It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. Pound-force per square inchĭefinition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. This is true of most countries, including the United States. The kilopascal is more prevalent in scientific contexts such as material science, engineering, and geophysics. Exceptions include certain countries that use either the imperial or United States customary systems of measurement, such as the United States, in which the unit of pound per square inch is more commonly used. In 1971, at the 14 th General Conference on Weights and Measures, the pascal was adopted as an SI derived unit of pressure.Ĭurrent use: The kilopascal is widely used worldwide in countries that have adopted SI. The kilopascal is simply a multiple of the pascal, as is common within SI. History/origin: The unit, pascal, is named after Blaise Pascal, a French mathematician and physicist. A kilopascal is defined as 1,000 Pa, where 1 Pa is defined as the pressure exerted by a 1 newton force applied perpendicularly to an area of one square meter, expressed as 1 N/m 2 or 1 kg/m Before we dive in, keep in mind that these formulas are just tools. PSI to BAR Conversion Formula: To convert PSI to BAR, divide the PSI value by 14.50377377.Formula: BAR PSI / 14.50377377. Definition: A kilopascal (symbol: kPa) is a multiple of the pascal (Pa), an SI (International System of Units) derived unit of pressure used to measure internal pressure, Young's modulus, stress, and ultimate tensile strength. PSI to KPA Conversion Formula: To convert PSI to KPA, multiply the PSI value by 6.89475729.Formula: KPA PSI 6.89475729.
