Hi, I am not a mathematician or scientist or student. In advance I ask that you please excuse my ignorance. I calculated that at tensile strength of .51 equals an MPA of .0035163. Thank god for internet calculators. I do not know what MPA means, but materials are listed this way. So if I want to choose a material with an MPA of greater than .0035163 and I look at the MPA of materials, the MPA listed seems mammoth in comparison and defies logic. For example, glass is listed as having an MPA of 60. So what am I missing?
