What is MPa (MPa)?
The megapascal (MPa) equals one million pascals, or 10 bar. It is used for material strength, high-pressure hydraulics and concrete specifications.
What is psi (psi)?
Pounds per square inch (psi) is the imperial pressure unit common in the US and UK, used for tyre pressure, air compressors and hydraulics. One psi equals about 6,895 pascals.
Why convert MPa to psi?
Pressure units differ by region and field: Europe uses bar, the US uses psi, science uses pascals and kilopascals, and medicine still uses mmHg. Converting between them is a daily need for mechanics, engineers and divers.
Standard atmospheric pressure is defined as exactly 101,325 Pa — equal to 1.01325 bar or 14.696 psi (BIPM/NIST). Car tyres are typically inflated to about 2.2–2.5 bar (32–36 psi).
