For example, you might convert a table of longitude and latitude values in decimal degrees (DD) to MGRS. With the CCN tool you can convert between DD, DDM, DMS, UTM, USNG, MGRS, GARS, and GEOREF. The tool takes your table of coordinates and converts them to point features with an attribute containing the new output notation.

How to convert DMS to decimal with Excel.

Working in civil engineering I run into many situations where I need to convert Degrees, usually as Latitude and/or Longitude, between decimal degrees and Degrees, minutes, seconds (DMS).Often this happens in using Lat/Long provided from the survey crew and then needing to use that information to look up government data (such as soils, or flood data).There are plenty of online converters, but I typically work in MS Excel so it is nice to have a formula or macro to perform the task.

Microsoft provides a cut and paste Visual Basic program to perform the conversion.It gives step by
step instructs to insert the code on the MS support site.This method works well, but can only be saved in spreadsheets that have macros enabled. This is not my favorite method.

You can read more about and get the code snippets here: Microsoft

Doing a Google search for the Excel formulas shows that there several ways to structure the formula.
The following is the method that I settled on and seems to work well for me.Hopefully it works for you or at least provides a good starting point.

Convert Utm Coordinates To Decimal Degrees In Excel

Typically, I am entering the numbers by hand, so I don’t have any specific formatting issues to work around.If you are getting your data in spreadsheet with an existing format, you may have to do some work to “strip” the right data out.Often, this is a simple text-to-columns operation that can found under the DATA tab.

I started with a simple 4 column x 6 row grid.

This let me label the row and column headings to be consistent.

Convert utm coordinates to decimal degrees in excel pdf

The first grouping has me enter the Decimal and then returns the DMS.The second grouping has me
enter the DMS, separated into individual cells (for convenience).I applied a light fill to the cells I enter data into.

Decimal	Degree	Minutes	Seconds
Northing	40.484963	40	29	5.8668
Easting	79.403523	79	24	12.6828
Northing	40.484963	40	29	5.87
Easting	79.403523	79	24	12.68

Next, I needed to come up with the formulas to do the conversions.

To convert from decimal to DMS:

you first need to strip the decimal portion away to be left with the degrees.I use the INT function for this because it rounds the number down to the closest integer.

The formula looks like this: =INT(B2)

2. To calculate the minutes, you need the decimal part of the original number times 60.I obtain that number by subtracting the integer from the original number.That returns a number with a fraction. again, we only want the integer part of the answer.

This formula looks like: =INT((B2-C2)*60)

3. Finally, to get the seconds, we need to get the decimal portion of the minutes and multiply that by 60.

The final formula is: =((B20-C20)*60-D20)*60we can keep this number as an integer with decimal.

See the completed table below.

Decimal	Degree	Minutes	Seconds
Northing	40.484963	40	29	5.8668
Easting	79.403523	79	24	12.6828

The table with formulas exposed looks like this:

Decimal	Degree	Minutes	Seconds
Northing	40.484963	=INT(B2)	*=INT((B2-C2)60)**	*=((B20-C20)60-D20)60*
Easting	79.403523	79	24	12.6828

If you want to be able to copy the DMS answer directly out to a web application or to a word document you can add a column to combine the separate cells and add in the text portions.

That formula is: =CONCATENATE(C2,”°”,D2,”‘ “,E2,””””) . Note the extra “ in the formula. Excel requires this to know that you want to add the quote as text.

To convert from DMS to decimal:

For this process, I left it that I enter the parts of the DMS into individual cells.This simplifies the formula.

I was able to compress the conversion formula into one step. Essentially we just need to divide each portion by 60 and add it to the next higher portion.Divide the seconds by 60 and add that number to the integer for the minutes.Then, that decimal is added to the degrees integer to give you the final result.

The equation is: =ROUND((E23/60+D23)/60+C23,6)I added the ROUND function here to control the precision of the answer, it is not strictly necessary.

Decimal	Degree	Minutes	Seconds
Northing	40.484963	40	29	5.87
Easting	79.403523	79	24	12.68

The table with formulas exposed looks like this:

Decimal	Degree	Minutes	Seconds
Northing	=ROUND((E23/60+D23)/60+C23,6)	40	29	5.87
Easting	79.403523	79	24	12.68

Note: The degree symbol is not simply a superscript “o”.To obtain a true degree symbol you hold the “ALT” key and type 0176.

Online UTM to Latitude Longitude converter

Convert from UTM - Universal Transverse Mercator - coordinates to latitude and longitude coordinates.

^*) Based on the WGS84 Datum - the calculator is valid for the northern hemisphere.

In the UTM coordinate system a grid is used to specify locations on the surface of the Earth. The UTM system is not a single map projection but instead a series of sixty zones. Each zone is based on a specifically defined secant Transverse Mercator projection. The units for both east and north coordinates are meters.

The UTM north coordinate is the projected distance from equator for all zones. The east coordinate is the distance from the central median.

European Reference System - ETRS89

Note that the World Geodetic System WGS84 and the European Reference System ETRS89 are virtually identical and that coordinate transformation between the two systems in practical navigation is unnecessary. However, for high-precision surveying work - be aware that the two systems deviates more than half a meter.

Convert a List of UTM Coordinates

You can use the tool below to convert a list of many UTM coordinate points to their latitude and longitude values.

Replace the coordinates below with a comma separated (CSV) list with one UTM point on every line. Click 'Convert!' to add latitude and longitude to the coordinates.

Note! - keep the first line in the text box untouched. if the converter outputs strange coordinates - check the sequence of input values (north first).

Copy the list with the latitude and longitude values and paste it into a spreadsheet, a text editor - or whatever you prefer - for further processing.

Tip! - If you have a csv list (or file) where the sequence of the input coordinates are in wrong order - open the csv list (or file) in a spreadsheet - move the columns with the coordinates to the right position according the required sequence - save the spreadsheet as a new csv file - open the csv file in a simple text editor - copy and paste the list into the input field above - Convert! The converter is valid for the northern hemisphere.
