Mpa in concrete design.
Mpa in concrete design.
(OP)
I know that Mpa is the metric SI equivalent of PSI. I know that the “M” stands for mega, meaning one million. I know the “pa” stands for “pascal”, which is one Newton of pressure/m². What I want to know is what this translates into in actual pressure. For example, in designing concrete, what pressure will 28 Mpa concrete stand up to? How is it calculated?

28 MPa concrete will withstand at least 28 MPa in compression.....or slightly more than 4000 psi. It is calculated as force per unit area.
Please don't design anything.

Take the load at failure (kN), divide by the area of the cylinder or cube (perpendicular to the loaded axis) which is in mm2. Determine the pressure kN/mm2 by Load/Area. Change kN to N and you have MPa.
