The Wikipedia page Decimal Degrees has a table on Degree Precision vs. Length. Also the accuracy of your coordinates depends on the instrument used to collect the coordinates - A-GPS used in cell phones, DGPS etc.

decimal places   degrees          distance
       0         1                111   km
       1         0.1              11.1  km
       2         0.01             1.11  km
       3         0.001            111   m
       4         0.0001           11.1  m
       5         0.00001          1.11  m
       6         0.000001         11.1  cm
       7         0.0000001        1.11  cm
       8         0.00000001       1.11  mm

If we were to extend this chart all the way to 13 decimal places:

decimal places   degrees          distance
       9         0.000000001      111  μm
       10        0.0000000001     11.1 μm
       11        0.00000000001    1.11 μm
       12        0.000000000001   111  nm
       13        0.0000000000001  11.1 nm
