Convert Atmosphere to Megapascal
Input the number of atmospheres you want to convert to megapascals.
How to Convert Atmospheres to Megapascals
The atmosphere and megapascal are both units of pressure. 1 megapascal equals 9.8692326672 atmospheres. This means to convert atmospheres to megapascals, you divide by 9.8692326672.
Formula
Step-by-Step Example
Convert 5 atm to megapascals:
We need to convert atmospheres to megapascals
Since 1 MPa = 9.8692326672 atm, divide by 9.8692326672
5 ÷ 9.8692326672 = 0.506625
5 atm = 0.506625 MPa

About These Units
Atmosphere (atm)
One standard atmosphere (atm) equals 101,325 Pascals, 1.01325 bar, or 14.696 PSI—the average air pressure at sea level. Atmospheres measure diving depth (every 10 meters adds ~1 atm), altitude effects, and chemical reactions. Used as a reference pressure in science.
Megapascal (MPa)
A megapascal (MPa) equals 1,000,000 Pascals or approximately 145 PSI. Megapascals measure material strength (concrete: 20-40 MPa, steel: 250+ MPa), hydraulic systems, and high-pressure applications. One MPa equals 10 bar.
