If you encounter any issues to convert Standard Atmosphere to psi, this tool is the answer that gives you the exact conversion of units. Converting atm to Pound Per Square Inch is easy, for you only have to select the units first and the value you want to convert. When you are converting pressure, you need a Standard Atmosphere to Pound Per Square Inch converter that is elaborate and still easy to use. helps in the conversion of different units of measurement like atm to psi through multiplicative conversion factors. Be it buying grocery or cooking, units play a vital role in our daily life and hence their conversions. Measurement like pressure finds its use in a number of places right from education to industrial usage. 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.ġ5 bar = 15 × 14.503773773 psi = 217.Units of measurement use the International System of Units, better known as SI units, which provide a standard for measuring the physical properties of matter. 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. Meteorologists and weather reporters worldwide often use this unit for convenience, since working in pascals would result in much larger values. 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. It is equal to 0.987 atmospheres (101,325 Pa), the unit often used as a reference of standard pressure. Definition: A bar (symbol: bar) is a metric unit of pressure that is defined as exactly 100,000 pascals (symbol: Pa).
