ConverTable Units2.8.4

Ah, yes, the Apple calculator app does tell the answers - and does do conversions. BUT, the years have taught me that "how" can occasionally be as important as "what". ConverTable Units tells me both "how"and "what". This app shows one how the answeres are derived. That is especially good for those of us who are math challenged and care about it. I suppose that the same might apply to students who are trying to understand math or parents of students who are trying to understand math. Good app.
