| | Universal Transverse Mercator(UTM) Grid, Fact Sheet 077-10 (August 2001) |
 | | The UTM grid is shown on all quadrangle maps prepared by the U.S. Geological Survey (USGS). |
 | | On 7.5-minute quadrangle maps (1:24,000 and 1:25,000 scale) and 15-minute quadrangle maps (1:50,000, 1:62,500, and standard-edition 1:63,360 scales), the UTM grid lines are indicated at intervals of 1,000 meters, either by blue ticks in the margins of the map or with full grid lines. |
 | | On maps at 1:100,000 and 1:250,000 scale, a full UTM grid is shown at intervals of 10,000 meters and is numbered and used in the same way. |
