In this post we will provide a calculator that can convert latitudes and longitudes from one format to another so you can enter it in a fish finder. Many fishermen use fish finders that allow you to enter a latitude and longitude “location” and the fish finder will display it on the navigation map. The problem you may encounter is someone provides the location coordinates in one format and your fish finder uses a different format.

#### Geo Location Formats

The converter supports three different formats and can convert between any two of them. In general, a latitude or longitude is expressed in Degrees, Minutes, and Seconds. A Latitude describes the distance you are from the equator and the Longitude describes how for east/west you are. Latitudes can either be expressed using East/West or a positive/negative number.

The three formats are:

- DD – Decimal Degrees. This is one number like 27.12345 that expresses the Degrees, Minutes, Seconds all in one number with a decimal value.
- DMS – Degrees with Minutes and Decimal Seconds. This is three numbers, the first being the Degrees and the second being the minutes and the third being the seconds with a decimal value. For example, 27 degrees 39 minutes 42.12345 seconds.
- DDM – Degrees with Decimal Minutes. This is two numbers, the first being the degrees and the second being the Minutes with a decimal value. For example: 27 degrees and 39.12345 minutes.

So in my case, a web site I use provides fishing locations in the DD “Decimal Degrees” format but my fish finder can only accept locations in DMS “Degrees with Minutes and Decimal Seconds”. My solution is to convert DD to DMS using the calculator below.
