This question already has an answer here:

For example, if the latitude and longitude is

25.1054, 121.5973

then what if it is off by a small amount, such as 0.0001:

25.1055, 121.5974

Then can it readily tell how many feet or meters it is off by?

    Not directly because lengths in degrees vs. meters vary. You will find loads of reading by searching "great circle distance" and "haversine formula". – user30184 Nov 28 '16 at 9:02
  • it is not 0.0001 translating to about 11.1 meters as in the answers of the other question? – 太極者無極而生 Nov 28 '16 at 18:33
  • If you are at latitude of 70 degrees you can check with this calculator csgnetwork.com/degreelenllavcalc.html that in East-West direction it translates to about 3.8 meters. – user30184 Nov 28 '16 at 19:17
