MPa
megapascal
Pressureexact by definition
The megapascal is exactly 10⁶ pascals, or 10 bar. The relation is exact. It is the standard unit of material strength, since one megapascal is exactly one newton per square millimetre, and concrete, steel and polymer strengths all fall in a convenient range when expressed this way.
Watch out: Concrete compressive strength quoted as "C30" or "30 MPa" refers to a characteristic strength from a standardised specimen, not a working stress. Design codes apply substantial partial factors on top, so a 30 MPa concrete is not permitted to see 30 MPa in service.
