Easting and northing are coordinates inside a particular projected CRS. The same numeric pair can refer to a completely different place if the zone, hemisphere, or datum changes. That is why this tool returns all three pieces alongside the meter values.

For WGS84, northern UTM zones use EPSG codes 32601–32660, while southern zones use 32701–32760. For example, WGS84 / UTM zone 17N is EPSG:32617.

UTM zone numbers run from 1 to 60. Latitude bands use the letters C through X, omitting I and O. The band is useful in a grid-zone designation, but it is not interchangeable with the N/S hemisphere suffix used in names such as “WGS84 / UTM zone 17N.”

Keeping those labels separate avoids a common ambiguity: “17N” can mean the northern-hemisphere projected CRS, whereas the latitude band at roughly 40°N is actually T.

The ordinary zone formula works for most of the world, but standard UTM includes widened zones around Norway and Svalbard. A converter that always applies only floor((longitude + 180) / 6) + 1 can assign the wrong UTM zone there.

Those exceptions are implemented in this calculator before the transverse Mercator projection is evaluated.

UTM easting and northing are projected coordinates, not simple ruler distances from a geographic line. Each zone's central meridian is assigned a false easting of 500,000 m, and the projection has a central scale factor of 0.9996.

In the southern hemisphere, 10,000,000 m is added as a false northing so ordinary UTM northing values remain positive. Treat the numbers as coordinates in the stated projected CRS rather than as literal “meters east of the meridian” or “meters north of the equator.”

This converter assumes the input latitude and longitude are WGS84 and produces WGS84 UTM coordinates. Feeding it coordinates from NAD27, NAD83, ETRS89, or another datum without the required datum transformation can shift the result.

Six decimal places are displayed so the numeric calculation is not prematurely rounded, but that display precision is not an accuracy guarantee. Real positional accuracy depends on the source coordinates, datum realization, measurement method, and the CRS required for the project.

For cadastral, engineering, or survey work, use the authoritative CRS and transformation workflow specified for the job. This calculator should not be used to infer survey-grade accuracy from low-accuracy latitude/longitude input.
