MPa Unit - Pressure, Stress, and Strength Metric Unit
MPa Unit Definition
The term MPa represents "megapascal", which is a pressure unit in the International System of Units (SI).
The M in MPa denotes mega, a prefix commonly used in the metric system meaning a million. Therefore, 1,000,000 Pa (pascal) equals 1 MPa.
MPa can be expressed in an equivalent form as N/mm² (newton per square milimiter): 1 MPa = 1 N/mm².
MPa Unit Usage
The unit of MPa is well adapted to conveniently indicate stress and strength of common construction materials.
The concrete used in buildings, bridges, foundations, or dams uses to have a compressive strength of 30 to 50 MPa.
The reinforcing steel bars used to provide tensile strength to concrete structures frequently have a yield strength of 400 to 500 MPa.
