When the first base is a value other than 1em, the 2nd em column shows up. This can be confusing as the calculator assumes your scale should start at 1em while also providing you a scale with values as you plugged them in. As a result, we have 2 columns of em values without much explanation as to why that is and what to use in what situation.
