How to get the accurate measurement result?

I am working on the measurement widget, and it seems that the out of box 'esri/dijit/Measurement' widget is always based on Web-Mercator projection. This makes the measurement result not as accurate as local projection if I understand correctly. Is there a way to use local projection to do the measurement by using this widget? Or I must build a fresh new widget from scratch by myself if I want to get accurate measurement result?
