This question already has an answer here:
I found this chart in one of the questions here. Additional to this: When making a measurement and getting 2 Measures of Latitude, for example 51.1901354 and 51.1901359. Is it then possible to say that these points are 5.55 cm apart? Also, I am using this formula to get meters rather then degree:
Northing = (Latitude-Base_Latitude)*(6378137*pi/180)
Easting =(Longitude-Base_Longitude)*(6378137*pi/180) * cos(Base_Latitude*pi/180)
Is the Chart above usable with this Convertion?
