So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Pascals then divide by the factor for B to convert out of Pascals. To convert from Pa into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.ĥ00000 Pa / 100000 = 5 bar Multiply by the conversion value in the right column in the table below.ĥ bar * 100000 = 500000 Pa To simply convert from any unit into pascals, for example, from 5 bar, just Where S is our starting value, C is our conversion factor, and How to Convert Units of PressureĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: DB Dino Buratti Keeping your tyre pressure where its supposed to be can cut down on your fuel bills and make your car safer to drive. You can use our converter to quickly change from one to another. Some are obvious, such as pounds per square inch, but even the SI standard Pascal is actually an expression of one Newton per square meter. Cars New and used cars Updated: BAR to PSI converter Two main pressure measurements are used for car tyres BAR and PSI. Since pressure is derived from force and area, many units for pressure directly relate force to area. Where P is equal to pressure, F is the normal force and A is area. You are at the right place, Bar to Psi online Pressure conversion formula chart, table to Kilojoule(kj) to Kilocalorie(kcal) online conversion calculator Formula to find an easy & quick conversion calculator.Īn online conversion calculator helps you convert all types of the measurement unit.Pressure is a scalar quality reflecting how force acts on a surface. If you are wondering, How to convert Kilopascal (Kpa) to Psi (pound per square inch) Pressure conversion formula. Although the pascal is more commonly used in scientific realms, pounds per square inch are used more often in everyday contexts-particularly in the United States and other countries that follow the US customary or imperial systems of units.ġ5 kPa = 15 × 0.1450377377 psi = 2.175566066 psiĪ unit converter is an online free tool that enables you to convert one unit of measurement into another. The pound-force per square inch is used to measure a myriad of things, including tire pressure, scuba tank pressure, natural gas pipeline pressure, and others. This style of weight was called the avoirdupois wool pound at the time. Narrow tires need more air pressure than wide ones: Road tires typically require 65 to 95 psi (pounds per square inch) mountain bike tires, 15 to 25 psi and gravel tires, 25 to 40 psi. The system is believed to have originated in England around 1300 and followed the international wool trade. It's based on the avoirdupois system, a system where the weight is based on one avoirdupois pound. Pound-force per square inch, often abbreviated as psi, is a unit of pressure that originated in the imperial and US customary systems. You can convert from psi to other units using our handy conversion tool. One psi is approximately 6,895 pascals (N/m2). The same holds true for Western countries, including the United States.Ī pound-force per square inch, or psi for short, is an imperial and US customary unit to measure pressure. The metric unit is more common in scientific contexts like material science, engineering, and geophysics. Motorcycle Tire Air Pressure Conversions. The use of kg/cm2 is a non-standard measurement. Atmospheric pressure is approximately 100 kPa. Potentially confusing exceptions include many countries that still use alternative systems of measurement, such as imperial units or United States customary units. Some motorcycle tire pressures are listed in psi (pounds-force/square inch), and others in kPa. Originally developed for use in SI, the kilopascal is now widely used worldwide. The kilopascal is simply an SI unit of pressure and was adopted in 1971. Conversion Calculator Enter your value in the conversion calculator below. Our conversions provide a quick and easy way to convert between Pressure units. Pascal is a unit of pressure that is named after Blaise Pascal, a French mathematician and physicist. Convert kPa to psi - Pressure Conversions Online calculator to convert kilopascals to pounds per square inch (kPa to psi) with formulas, examples, and tables. A kilopascal is equal to 1,000 Pa, where 1 Pa is defined as the pressure at which a load of one newton acts perpendicularly on an area of one square meter and it's expressed as 1 N/m2 or kg/m They are told as kilo, followed by the pascal (Pa), which is an SI derived unit of pressure.
