Compressive strength is the maximum stress a material can sustain under pushing, crushing forces. The compressive strength of a material is determined by the shattering fracture of the material under these forces. Compressive stress is calculated by dividing the maximum load by original cross – sectional area of the sample.

In the United States concrete strength is measured in pounds per square inch or psi. In Europe concrete strength is usually measured in megapascals which is abbreviated MPa. Both 32 MPa and 5000 psi are minimum strengths. 5000 psi concrete that actually tests at 5600 psi is not defective. And 32 MPa converts to 4643 psi.
