Psi to bar10/26/2022 ![]() The following key terms may be beneficial when dealing with your gauge: psi, kPa, BAR definitions. You can find high- and low pressure fittings, tubing and connectors in our online shop. above atmospheric pressure (which is around 1 BAR). ![]() For more exact data, please use the conversion factors: 1psi = 68.9476 mbar 1bar = 14.5038 psi Converting pressure from pounds per square inch to bars Use our accurate and simple psi to bar pressure converter for calculations. For your convenience we provide easy pressure conversion tables between psi (pounds per square inch) and bar (mbar) and from bar (mbar) to psi. Psi to Kilopascal Conversion Table Psi ġ5 psi = 15 × 6.8947572932 kPa = 103.The fluid transfer community uses both, the metric system (international System of Units) as well as the English system (U.S customary system) for pressure data. This is true of most countries, including the United States. Bars are used in the metric system, and psi (pounds per square inch) are based on the avoirdupois system (thats. 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. 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). 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. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi. 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. Learn more about what the different tyre pressure measures are. 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 Use the convenient TyreSafe tyre pressure conversion chart to convert Bar to PSI & KPA. Kilopascalĭefinition: 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. Note that rounding errors may occur, so always check the. You can view more details on each measurement unit: bar or psi The SI derived unit for pressure is the pascal. We assume you are converting between bar and pound/square inch. 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. How many bar in 1 psi The answer is 0.0689475728. 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. 200 Kilopascal to Psi: 200 Psi psi 13.789514586357 Bar : 200 Psi to Bar: 200 Bar to Psi: 200 Psi psi 0.2 Ksi ksi 200 Psi to Ksi: 200 Ksi to Psi: 200 Psi psi 13.609192781995 Standard atmosphere atm 200 Psi to Standard atmosphere: 200 Standard atmosphere to Psi: 200 Psi psi 1. 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. 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. 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. Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. ![]()
