atm to MPa converter
1 atm = 0.101325 MPa
And 1 MPa = 9.86923 atm. Standard atmosphere to megapascal.
Formula
MPa = atm × 0.101325
A reading of 15 atm is 15 × 0.101325 = 1.51988 MPa.

About these units
atm (standard atmosphere): Defined as 101,325 Pa, roughly sea-level air pressure.
MPa (megapascal): Standard for material strength, hydraulics and pressure vessels; equal to 1 N/mm².
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
