# Lat Long to UTM Converter

This lat long to UTM converter takes the familiar latitude and longitude coordinates and converts them to the **Universal Transverse Mercator (UTM) coordinate system**.

The article below explains what UTM is and how to use this UTM coordinates converter. So, let's get going and convert lat long to UTM coordinates.

## What is Universal Transverse Mercator (UTM)?

UTM is a grid-based mapping system made up of **60 separate transverse Mercator projections (called zones)**, each is 6° wide to cover the full 360° of longitude (east/west direction). Due to the increased curvature of the Earth near the poles, UTM only covers latitudes (north/south direction) from **80° south to 84° north**.

The **first part** of a UTM coordinate is the **zone number (1 to 60)**. Zone 1 is placed at 180° W longitude (at the International Date Line) and counts up going eastward.

The **second part** indicates whether the position is **north or south of the equator**. UTM indicates north by the letter "N" and south with the letter "S". That's simple enough.

Now things start to get complicated. The next part of a UTM coordinate is called the **easting**, which is the distance in meters from the central meridian (which in the middle of a zone along the east/west axis). However, to avoid negative numbers, an easting is measured from **500,000 meters west of a zone's central meridian**. At the equator, easting values ranges from 166,021 m to 833,978 m. As you move away from the equator, the zone width gets narrower and so this range decreases.

The final part of a UTM coordinate is the **northing**. For coordinates in the northern hemisphere, the **northing is the number of meters from the equator**, up to a maximum of 9,329,005 m at 84° N. For the southern hemisphere, **northing is measured from 10 million meters south of the equator**. Since UTM does not apply to positions south of 80° S, a northing in the southern hemisphere ranges from 1,116,915 m to 10,000,000 m at the equator.

Easting and northing values are **rounded to the nearest meter.** There is not much point using more precision than that, as then plate tectonic movements start to become important.

## Latitude band letters and grid zone designator

There is another, non-standard, component of a UTM called a latitude band. It is part of another system of representing UTM coordinates called the **Military Grid Reference System (MGRS)**. However, because many resources give the latitude band as part of the UTM, we also provide it as one of the outputs of this lat long to UTM converter.

There are **20 latitude bands**, each 8° tall (except band "X", which is 12° tall). We letter the bands from "C" in the south (at 80° south) to "X" at 84° north. Note that we skip the letters "I" and "O" to avoid any confusion with the numbers one and zero.

In the MGRS system, a combination of the UTM zone and latitude letter is called the **grid zone designator (GZD)**, which is what the UTM coordinates converter also reports.

## How to use this UTM coordinates converter? - convert lat long to UTM coordinates

So, this is how you convert lat long to UTM coordinates with our calculator:

- Enter the
**latitude**of the location you want to convert to UTM. Use positive**values up to 84°**for positions in the northern hemisphere and negative**values down to -80°**for locations in the southern hemisphere. - Enter the
**longitude**of the geographical coordinate you wish to convert to UTM. Use positive values for points east of Greenwich, London**(up to a value, but not including, 180°)**and negative values for longitudes west of Greenwich,**down to a value of -180°**. - The lat long to UTM converter then displays the
**UTM zone, hemisphere, easting, and northing**separately. - This UTM coordinates converter also shows the
**complete UTM coordinate standard notation**. - As a bonus, the converter shows the
**grid zone designator**from MGRS, as some non-standard UTM notations include it.
