Are units like MPa or psi not commonly understood by the science-curious public?

Well no, nor is the term "strength". Is it yield strength, fracture toughness, youngs modulus, etc, etc? Is that tensile, compression or shear you are talking about? Carbon fibre is strong, but how about if you hit it with a brick, then normal wood is "stronger". And then there is anisotropic behavior... This stuff is complex.
