Tire pressure. On the table is PSI, which is the imperial tire pressure marking, not the SPI.
Our common tire pressure mark is kilopascals or kilograms, which is converted to 1 MPa (megapascals.
145 psi, 1 kg = 100kPa (kilopascals). For small cars in general.
For example, the tire pressure is mostly hit to kilograms (that is, between 200-280 kPa (200-280kpa), specifically refer to the logo on the fuel tank cap or tire, as well as the introduction of tire pressure on the manual.
Like the logo on the tire pressure gauge, most of them are psi, kpa, kg, according to the above method to pump, just maintain the right tire pressure.

Although the tire pressure gauge is varied, the tire pressure gauge we usually use is generally marked with two air pressure units.
As shown in the figure, the red unit in the inner circle is psi (pounds square inches), and the unit in black in the outer circle is kg cm 2 (kilogram square centimeter), which is the bar marked in the figure. The standard unit in the International System of Units is the newton square meter, which is the newton square centimeter, or kilogram square centimeter. Therefore, what we usually call a pressure is bar.
This is the other one, and the reading is the opposite of the image above.
We can find the tire pressure prompt required by the manufacturer in the fuel tank cap or under the B-pillar of the door, and inflate it according to the air pressure required by the manufacturer.
When the tire pressure is not enough, there is a warning light on the car instrument to remind the drivers that the tire pressure is not enough, the warning light is a flat circle at the bottom, and an exclamation mark is added in the middle to indicate.
Vehicles without tire pressure monitoring will experience some conditions that are not normally present on the vehicle's operating experience. When the tire pressure is insufficient, it will turn a little heavier than usual, and the range of the vehicle will be a little higher than usual. And when the tire pressure is insufficient, when passing over some potholes or car stoppers, the experience of the vehicle will be different, and the jump of the car in the past tense will be different from usual.
Insufficient tire pressure will cause the total area of the tire to be in contact with the road surface to increase, and therefore the wind noise heard in the car will also increase.
When the tire pressure is insufficient, it will cause certain harm to our safe driving or tires, and the key is to expand the contact area between the tire and the ground, increase the friction resistance, and increase the damage level of the tire, thereby reducing the service life of the tire, and continuing to increase fuel consumption. The intensity of the movement of the various parts of the tire increases, and excessive rolling occurs, which further causes the tire to become abnormally hot.
It will make the steering wheel of the car sinking, and it is very easy to deviate from the direction and other factors that are not conducive to driving safety.

The unit is bar.
The unit of measurement for air pressure.
Generally, there are five types: kg cm2, bar, kpa, psi, and atmospheric pressure. The conversion relationship between them is:
1kg/cm2=
1 atm = kg cm2
In order to make it easy to remember and convert, it is recommended that you use the commonly used kg cm2, bar, kpa, and atmospheric pressure as daily measurements of tire pressure.
The conversion relationship between them can be simplified as: 1kg cm2 1bar 100kpa 1 atmosphere.
Tire pressure refers to , so = .
psi is a unit of pressure.
Defined as the pound sterling.
square inches, 145psi = 1mpa
The full name of psi in English is pounds per square is pound, s is square square, and i is inch inch. Replace all units with metric units to calculate: 1bar, 1psi= Europe and the United States and other countries are accustomed to using psi as a unit.
In China, we generally describe the pressure of the gas as "kilogram" (not "jin"), the body unit is "kg cm 2", and one kilogram of pressure is the force of one kilogram acting on a square centimeter.
The commonly used unit in foreign countries is "psi", and the specific unit is "lb in2", which is "pound square inch", which is like the Fahrenheit temperature scale (f).
In addition, there is PA (Pascal.
One Newton. acting on one square meter), kpa, mpa, bar, millimeter water column, millimeter mercury column.
Equal pressure units.
1 bar = megapascals (mpa) = 100 kilopascals (kpa) = kilograms square centimeters.
1 standard atmosphere.
ATM) = MPa) = Bar
Because the difference between the units is very small, and you are not an engineer. So, it can be written like this:
1 bar = 1 standard atmosphere (atm) = 1 kilogram square centimeter = 100 kilopascals (kpa) = megapascals (mpa).

The red outer ring is the pound square foot. The inner circle is black in kilograms square centimeters. Everyday words or equal refer to the black numerals in the inner circle.
The red on the outer ring is the imperial unit psi (pounds square inches), the black inner ring is measured in kg cm 2 (kilogram square centimeter), and the standard unit in the International System of Units is n m 2 (newton square meter), which is pa. A standard atmosphere is about pa, which is Newton square centimeters, i.e., kilograms square centimeters. Roughly speaking, a standard atmosphere is the position of the black 1 on the watch.
Data expansion: Tire pressure gauge or tire pressure gauge is a special pressure gauge that is used to measure the pressure in the tires of cars, trucks, bicycles, etc. The tire pressure gauge uses pressure sensing technology to achieve high measurement accuracy (less than the error and long service life. Using a tire pressure gauge to test the tire pressure in time can enable motorists to know the tire pressure of their car tires in time.
The pointer type is easy to operate, the digital reading is convenient, and the alarm type does not display the tire pressure value. Each tire pressure gauge has a certain pressure measurement range, generally household only 0-100psi, no need for trucks and other heavy-duty tire pressure gauges, ** from 12 yuan to 100 yuan.

Answer hello,There is a pointer type air pressure gauge linked to the tire pores, the greater the pressure in the tire, the more biased the pointer, and there is a reading. Generally speaking, there are 3 types of air pressure, psi, bar, kpa: psi = 100kpa = 1 bar.
2.The air pressure of the general sedan can be seen when the driver's door is opened, between the bar.
Look at the inner circle. Ask what the outer ring is.
What is the outer ring.
1. The angle between the center line of the air pressure measuring port and the surface axis is 90°-180°, the ruler is quadrilateral, and the scale value of the measuring range is. Gently snap on the instrument housing or surface glass with your fingers before reading to eliminate friction in the transmission mechanism;
2. When observing, the pointer overlaps with the mirror pointer, and the index value of the pointer is the value of barometric pressure, and the reading is accurate to one decimal place. Read the temperature indication on the barometer to one decimal place;
3. The barometer measures the end groove and the tire valve to positive pressure. At this time, the tire pressure gauge pointer is deflected, and its indicated value is the tire inflation pressure, or the tire pressure is introduced under the action of air pressure, then the value displayed on the reference is the tire inflation pressure, and the greater the pressure in the tire, the greater the pointer deflection.

Open the tire valve cap, connect the tire pressure gauge valve to the tire valve, press until the pointer reaches the highest value and start reading the tire pressure.
You can see that there are two turns of the tire pressure gauge, one is the imperial unit psi (pounds square inches), and the other is kg cm 2 (kilogram square centimeter), and we usually refer to the black number of the inner ring.
Classification of tire pressure gauge is generally divided into three kinds, namely analogue tire pressure gauge, digital tire pressure gauge and alarm tire pressure gauge, the latter two can tell us the tire pressure through numerical values or alarms, and the principle is relatively simple.
And we have seen the most in our daily life is the pointer tire pressure gauge, as long as it is connected to the tire valve can check the tire pressure of the car, and then by looking at the pointer of the head of the gauge to understand the tire pressure, although the pointer tire pressure gauge is also simple, but unfamiliar friends are prone to misreading, so let's take a look at the pointer tire pressure gauge how to see.

Many people don't know how to read tire pressure gauges, including those who sell tire pressure gauges.
The red outer ring is the pound square foot. The black kilogram of the inner circle square centimeter What we call or equal in daily life refers to the black number of the inner circle.
It is enough to master the above, if you want to know, look at the following in detail:
The red on the outer ring is the imperial unit psi (pounds square inches), the black inner ring is measured in kg cm 2 (kilogram square centimeter), and the standard unit in the International System of Units is n m 2 (newton square meter), which is pa.
A standard atmosphere pressure is about.
Pa, which is Newton square centimeter, is kilogram square centimeter. Roughly speaking, a standard atmosphere is the position of the black 1 on your watch, and to be more precise, it should be at that place on your watch.

Tire pressure. bar is the imperial unit of pressure.
Bar is a unit of tire pressure. psi is a unit of pressure.
It is a pressure unit commonly used in Europe and the United States and other countries.
Generally, there are two types of analog barometers, black and red, the unit of black is kg cm2, and the unit of red scale is psi. where kg cm2 is the unit of pressure, and psi is an expression of pressure, which specifically means how much force is on top of each square inch. Different countries use different methods, but they can all be used to indicate tire pressure.
According to the conversion formula: 1 bar = 100kpa=, you can read the tire pressure value on the tire pressure gauge.

Barometers are used to measure the pressure of a gas and are usually expressed in two units, bar or psi. bar is the unit of pressure in the International System of Units, its full name is bar, and 1 bar is equal to 10 5 Pa (Pascal), which is 1 standard atmosphere. psi is the unit of pressure in the imperial system of units, and its full name is pound-force square inches, and 1 psi is equal to about bar.
In some countries and industries, psi is commonly used to indicate gas pressure.
On barometers, two units are often printed, such as "0-10 bar 0-150 psi", indicating that the barometer measures in a range between 0 and 10 bar or 0 to 150 psi. Therefore, when using a barometer, it is necessary to select the corresponding unit according to the actual needs and convert it at the time of measurement, so as to measure the pressure of the gas more accurately.
