You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭonversion calculator for all types of measurement units. ![]() The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. .7572931783 Pa 1 Pa 0.0001450377 psi Example: convert 15 psi to Pa: 15 psi 15 × 6894.7572931783 Pa 103421. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The definition of a pascal is as follows: The SI prefix "kilo" represents a factor of A 1-m3 tank containing air 25 oC & 500 kPa is connected to another tank. PSI to kPa, or enter any two units below: Enter two units to convert From: Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values.You can do the reverse unit conversion from Millibars (symbol: mb) are also commonly used when referencing atmospheric air pressure, where atmospheric pressure equals 1013.25 mbar (101.325 kPa). The International Bureau of Weights and Measures has specified the bar as a unit that authors should have the freedom to use but has chosen not to include the bar in the list of non-SI units accepted for use with SI. The term "bar" comes from the Greek word "baros," which means weight.Ĭurrent use: Although the bar is a metric unit of pressure, it is not accepted within the International System of Units (SI) and is even deprecated within certain fields. History/origin: The unit, bar, was introduced by Vilhelm Bjerknes, a Norwegian meteorologist who founded modern weather forecasting. inch (KPa to psi) Divide pressure/stress in KPa by 6.89476 The result is the pressure/stress in psi For. How to convert kilopascal to pounds per sq. It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure. inch to kilopascal (psi to KPa) Multiply pressure/stress in psi with 6.89476 The result is the pressure/stress in KPa For example 10psi is 10圆.89476 68.95 KPa. Barĭefinition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa). This is true of most countries, including the United States. So you want to know how many kilopascals in a psi Kilopascal (Kpa)is a pressure. The kilopascal is more prevalent in scientific contexts such as material science, engineering, and geophysics. psi (Pound force per square inch) to Kilopascals (KPa) Conversion. 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. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. 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. For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. 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 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.
