Regarding hydraulic hoses, we often encounter two critical units: MPA and PSI. Here is a concise explanation of the two units:
Both MPA and PSI are units for measuring pressure.
MPA stands for megapascals, and PSI stands for pounds force per square inch.
Pressure in hydraulic hoses is usually expressed in MPA or PSI. These two units can be converted into each other through the following conversion relations:
1MPA ≈ 145 PSI.
MPA is a relatively large unit describing pressure in high-pressure hydraulic systems. For example, the pressure to which a hydraulic hose is subjected may be expressed in megapascals, such as 200MPA.
PSI is a smaller unit used to describe lower-pressure applications. For example, the air pressure of a car tire is often measured in PSI, such as 30PSI.
In summary, the pressure in hydraulic hoses is measured in MPA and PSI.
MPA is used in high-pressure hydraulic systems, while PSI is used in lower-pressure applications.
