I have a shapefile and their X and Y coordinates' values are in Decimal Degrees. I want it to convert it in meters. 

I also tried to use Calculate Geometry tool. But as you might see it from below screenshot, I am only getting a single unit, i.e., Decimal Degrees under the ***'Units'*** drop down.
