A facility for converting latitude/longitude co-ordinates to co-ordinates in metres on a
Transverse Mercator projection.
The results of using the calculator provided on this page are believed to be accurate to 1
metre, but the accuracy is not in any way guaranteed.
The results will certainly not, however, be accurate to 1 metre in situations where lat/long co-ordinates are based on a geodetic datum which is different from that used in the selected conversion.
Do not enter negative values for lat/long co-ordinates west of Greenwich or south of the
equator. Specify W or S instead.
There are few validity checks on the input data.
For UTM conversions, the option exists for automatic calculation of the Central Meridian or manual entry of the Central Meridian. The calculation assumes that the standard UTM longitude zones are 6 degrees wide, except for the special zones around Svalbard and south-west Norway. For projections outside of the standard UTM zones you should manually enter the Central Meridian for the projection required.
