Understanding Units In FEA: “What In The Blob Is A Slug???”

Have you ever performed an analysis on a seemingly robust structure only to discover stresses that exceed the allowable limit by orders of magnitude? As experienced analysts, this is likely a problem you rarely encounter; however, when first delving into CAE, many engineers run into confusion when interchanging between unit systems. So, why does this
