Approximate Metric Equivalents for Degrees, Minutes, and Seconds

At the equator for longitude and for latitude anywhere, the following approximations are valid:

1° = 111 km (or 60 nautical miles)
0.1° = 11.1 km
0.01° = 1.11 km (2 decimals, km accuracy)
0.001° =111 m
0.0001° = 11.1 m
0.00001° = 1.11 m
0.000001° = 0.11 m (7 decimals, cm accuracy)
1' = 1.85 km (or 1 nautical mile)
0.1' = 185 m
0.01' = 18.5 m

0.001' = 1.85 m
30" = 900 m
15" = 450 m
3" = 90 m
1" = 30 m
1/3" = 10 m
0.1" = 3 m
1/9" = 3 m
1/27" = 1 m

=>If you report a position to the nearest 0.01° (two decimal places for latitude and longitude), you will only be accurate to around 1 km. While this is adequate for rough locations on a global scale, for detailed work it will be inadequate.
