What is Pound per square inch?

The pound per square inch is a unit of pressure expressing force in pounds-force applied to an area of one square inch. It is widely used in the United States and United Kingdom. Car tire pressure in the US is typically 30 to 35 psi, and industrial compressed air systems commonly operate at 90 to 150 psi. Fire sprinkler systems, natural gas pipelines, and hydraulic tools all use psi ratings. One psi equals approximately 6,895 pascals.

What is Megapascal?

The megapascal equals one million pascals and is widely used in materials and structural engineering. Concrete compressive strength typically ranges from 21 to 35 MPa, and steel tensile strength ranges from about 400 to 800 MPa. Hydraulic equipment operates at pressures of tens of megapascals. The unit is essential for specifying material properties, bolt preloads, and pressure vessel ratings in industrial applications.
