the pressure relative to the atmosphere, then you should use How many kPa in 1 PSI? What happens if you inflate your tires to the max PSI? Convert pressure values from kPa units to psi pressure units using the following method: 1 psi = 6894.76 Pascals (Pa) 1 kPa = 1000 Pascals (Pa) psi value x 6894.76 Pa = kPa value x 1000 Pa; psi value = kPa value x 0.145038; kPa pressure related products. Plus one size is 195/55R-15 with a recommended air pressure of 220 kpa. The system is believed to have come into use in England around 1300 and was used in the international wool trade. As such, the prototype pound at the time was known as the avoirdupois wool pound. 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. kPa to zeptopascal The answer is 6.89475728. PSI (relative to atmosphere). The SI prefix "kilo" represents a factor of 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. Millimeter, Kilopascal to Ton-force (long)/square Foot, Kilopascal to Ton-force (long)/square Inch. assuming you are measuring psia, which is the pressure relative The above form works if you are measuring differential You can view more details on each measurement unit: kPa to foot of head to use the unit converter.

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. inch, 100 kg, US fluid ounce, 6'3", 10 stone 4, cubic cm, conversion calculator for all types of measurement units. Tire air pressure decreases naturally (little by little). 1 pascal is equal to 0.001 kPa, or 0.00014503773800722 PSI. History/origin: The unit, pascal, is named after Blaise Pascal, a French mathematician and physicist. kPa to zettapascal Examples include mm, Definition: A pound-force per square inch (symbol: psi) is an imperial and US customary unit of pressure based on avoirdupois units. kPa to kilonewton/square meter If it is necessary to check tire pressures when the tires are warm, expect the pressures to have increased by up to 4 - 6 psi (0.3 - 0.4 bar, 30 - 40 kPa). kPa to decibar ConvertUnits.com provides an online Do not reduce the tire pressures to the cold inflation pressure under these circumstances. kPa or First thing in the morning or after sitting for a few hours in the shade is best. You can view more details on each measurement unit: kPa or PSI The SI derived unit for pressure is the pascal. 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. One psi is approximately 6,895 pascals (N/m2). Note how the air pressure increases with plus sizing to meet the load carrying capacity for the car. Type in your own numbers in the form to convert the units! Factors Impacting Your Tyre Pressure . We assume you are converting between kilopascal and pound/square inch. Current use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. One of the reasons for messuring gas pressure is to keep a constant supply.
