![]() ![]() 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. ![]() Suppose you want to convert 89 bar into pounds per square inch. 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. Here is the formula: Value in pounds per square inch value in bar × 14.503773800722. 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 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. 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. Using the conversion formula above, you will get: Value in psi 0.8 × 14.503773800722 11.603 pounds per square inch. Suppose you want to convert 0.8 bar into pounds per square inch. It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. Here is the formula: Value in pounds per square inch value in bar × 14.503773800722. To convert bar to psi, multiply the bar value by 14.5037738. 52-mm Ø instruments equipped with ring 27.499.03 or 27.599.03.ĪA - The revolution counters have to be equipped with: cable 27.599.11 (RPM counter function, only) additional cable 27.599.12 for other functions: hour counter, clock, voltmeter push-button 27.599.13 necessary for basic and advanced programming of the RPM counter.ĮE - The synchronizers have to be fitted with cables 27.599.11 + 27.599.12.īB - The sumlogs have to be equipped with:cable 27.599.11 (speedometer function, only) additional cable 27.599.12 for other functions: partial/total mile sumlog, depth sounder, water temperature, clock, voltmeter + push-button 27.599.13 multifunction transducer 27.581.50.ĬC - The 52-mm Ø control instruments have to be equipped with: cable 27.599.11ĭD - The rudder angle metres have to be equipped with: sensors 27.176.00 / 27.176.10 + cable 27.599.11.Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. 1 Bar is equal to 14.5037738 pound force per square inch (psi). ![]() RPM counter and sumlog equipped with ring 27.499.01 or 27.599.01.
