The datum is the mathematical model for the shape of the earth used in drafting a map. You can see the effect of datum changes by computing a conversion, then clicking different datum selections. Grid coordinates can change by several hundred meters.
D5
Type in the latitude and longitude, either in decimal form or degrees, minutes and seconds (DD:MM:SS). If you input both formats, only the decimal value will be used. The cells below will show coordinates converted into both formats. Input latitude and longitude as positive and select the appropriate hemisphere.
B15
The conversion from latitude and longitude to UTM is probably accurate to a meter or so. The reverse conversion is a bit less accurate, but is generally accurate within ten meters. Check accuracy for your purposes by inputting one set of coordinates, then converting back. See how close the values are to the original values
D16
Type in the UTM Grid goordinates. For complete conversion, you must also input the zone number (see your map legend) and the hemisphere. If no zone is imput, zone 31 (0-6 degrees) will be the default.
