Precision of the Geographic Coordinates in TIGER Files
Consider that the 90-degree angle from the equator to the North Pole (latitude) is about
10,000 kilometers. So:
A degree of latitude is about 111 kilometers.
A tenth of a degree of latitude is 11.1 kilometers.
A hundredth is 1.11 kilometers or 1110 meters.
