What is the unit conversion for tire pressure values?

[VanJude]

Tire pressure values represent the air pressure in the four tires, with the most commonly used unit being bar. Below are specific introductions about tire pressure monitoring: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. Wireless transmitters send pressure information from inside the tire to a central receiver module, which then displays the pressure data for each tire. Indirect tire pressure monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system achieves the purpose of monitoring tire pressure.
