It is generally accepted that air pressure in tires on a passenger car decreases by 5–10% (10–20kPa) every month. One of the reasons for messuring gas pressure is to keep a constant supply. kPa to zettabar PSI (relative to atmosphere). 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). A tyre under inflated by 20% gives 20% less mileage. We assume you are converting between kilopascal and pound/square inch. Millimeter, Kilopascal to Ton-force (long)/square Foot, Kilopascal to Ton-force (long)/square Inch. Tire size:195/65R 15 Starting pressure:220kPa(100kPa=1.0kgf/cm 2) (A) Air pressure(kPa) (B) Decreases by 10-20kPa a month; Impact of low air pressure on fuel consumption. The SI prefix "kilo" represents a factor of 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. kPa to inch water column to absolute zero vacuum. kPa to decibar Mercedes Benz Tyre Pressures, Tire Sizes and Torque settings Select the Model of Mercedes A Class B Class C Class C Class AMG 63 C Class Hybrid CL Class CLA CLC Class CLK CLS Citan E Class E Class Coupe GL Class GLA GLC GLE GLE AMG 63 S GLK GLS ML R Class S Class S Class AMG S63 S Class AMG S65 SL SLK Sprinter Sprinter Single Rear Sprinter Twin Rear V Class Vaneo Viano Vito X Class kPa to foot of head Improperly inflated tyres pose a real risk to the safety on the road. the form below. symbols, abbreviations, or full names for units of length, For example, US Federal Motor Vehicle Safety Standard (FMVSS) requires a warning if tires are under inflated by more than 25%. Tire air pressure decreases naturally (little by little). You can do the reverse unit conversion from Plus two size is 205/45R-16 with a recommended air pressure of 248 kpa. Please enable Javascript 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. the pressure relative to the atmosphere, then you should use 103, or in exponential notation, 1E3. Choose a value between 0 and 1000 kPa from the pressure conversion table below, to obtain the converted value in psi. assuming you are measuring psia, which is the pressure relative What if my tyre pressure is incorrect? As such, the prototype pound at the time was known as the avoirdupois wool pound. kPa to zettapascal

Examples include mm, PSI to kPa, or enter any two units below: kPa to nanobar The kilopascal is more prevalent in scientific contexts such as material science, engineering, and geophysics. It is defined as the pressure that results when a force of one pound-force is applied to a one-square-inch area. kPa to barad. The kilopascal is simply a multiple of the pascal, as is common within SI. 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. The right tyre pressure has a positive influence on some key areas of performance, including: - Improving your tyre lifespan - Decreasing your fuel consumption - Safe driving. One psi is approximately 6,895 pascals (N/m2). PSI

Type in your own numbers in the form to convert the units! History/origin: Pound-force per square inch is a unit that originated in the imperial and US customary systems of units. area, mass, pressure, and other types. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. Enter a pressure in kPa below to convert it to the equivalent pressure in psi. Factors Impacting Your Tyre Pressure . 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. kPa (relative to vacuum) The above form works if you are measuring differential Note how the air pressure increases with plus sizing to meet the load carrying capacity for the car. 1 kPa = 0.1450377377 psi1 psi = 6.8947572932 kPa, Example: convert 15 kPa to psi:15 kPa = 15 × 0.1450377377 psi = 2.175566066 psi, Kilopascal to Kilogram-force/square Meter, Kilopascal to Kilogram-force/sq. conversion calculator for all types of measurement units. as English units, currency, and other data.
