2 Simple Ways to Convert Latitude and Longitude to Decimal Degrees in Excel

There are many ways we can convert latitude and longitude data to decimal degrees. Here, we are listing a couple of easy but handy ways.

1. Using Manual Process

We will use basic mathematical procedures to convert Latitude and Longitude data to Decimal Degrees.

For that, let us have a sample data set.

dataset to convert into Decimal Degrees

Step 1:

For this method, we have to separate Degree, Minute, and Second values in different columns, and restructured the data table.

Here, we added a new column DD to store the converted result.

Now write the following formula in G5 and press ENTER.

=D5+E5/60+F5/3600

Convert Latitude and Longitude

And we will get the value in Decimal Degrees.

Step 2:

Now, Hold and Drag the G5 cell downward.

Thus, we will get values in Decimal Degrees for other cells as well.

2. Using String Manipulation Functions

String Manipulation using LEFT, MID, and FIND function is an easy way to convert DMS values to Decimal Degrees. Even though it is a complex formula, it is comparatively easy to use.

Step 1: 

First, add two columns where Decimal outputs will be shown.

Then, write the following formula in E5 and press ENTER.

=LEFT(C5, FIND("°",C5,1) - 1)+(MID(C5,FIND("°",C5,1)+1,(FIND("’",C5,1)-FIND("°",C5,1))-1)/60)+(MID(C5,FIND("’",C5,1)+1,(FIND("”",C5,1)-FIND("’",C5,1))-1)/3600)

Here, the LEFT function fetches the values ahead of “°”. First MID extracts the portion between “°” and “’”. Then last the MID function portion extracts the value after “’”. After extracting the values it sums them to produce the final value. The FIND function helps to initiate the search for the desired character within each portion.

By doing so, we get our first Decimal value.

Now, Hold and Drag E5 downward.

thereby we get all the Decimal values.

Step 2:

For Longitude,

Write the following formula in F5 and Press ENTER.

=LEFT(D5, FIND("°",D5,1) - 1)+(MID(D5,FIND("°",D5,1)+1,(FIND("’",D5,1)-FIND("°",D5,1))-1)/60)+(MID(D5,FIND("’",D5,1)+1,(FIND("”",D5,1)-FIND("’",D5,1))-1)/3600)

convert for Longitude

This formula works exactly the same as the previous formula.

By doing so, we get our first Decimal value in Degrees. Then, Hold and Drag the F5 cell downward.

And, we get all other Decimal Degrees.
