What are the units of the M value from MapPoint?

I am using Esri libraries in a Xamarin Android (C#) project. I'm pulling a list of MapPoints from a PolyLine and examining the M value. As the number is increasing while I traverse the list, I assume it is a cumulative total distance measure of some sort from the origin point. No matter what kind of tweaking and torking I do though, I can't make this value look like the total distance, or even get to the same order of magnitude. I've tried degrees -> km, and various other attempts at conversion. (I'm in WGS84 spatial reference).
