Whether you are using Google Maps, GSAK or geocaching.com, sometimes you need to convert a set of coordinates from the latitude / longitude format to the decimal format.

This can be accomplished by using a calculator.

Typicially, geocaching.com displays coordinates in the latitude/longitude format using the WSG84 datnum. This will take the form of:

** N/S HDDD MM.MMM**

**W/E HDDD MM.MMM **

When you are using mapping applications such as GSAK, Google maps, MSN Mapppoint, or Mapquest; you might need to convert this format to the decimal format.

The decimal format takes the form of:

**+- DD.MMM** (where **S** and **W** are negative)

For example, we have the following sets of coordinates:

**N 43° 48.225 W 079° 59.074**

To convert this to the decimal format, we start by keeping the **DD** portion and simply divide the **MM.MMM** by 60 to firm the **MMM** portion of the decimal format.

*43. (48.225/60), -79.(59.074/60)* **=** *43.(0.80375), -79.(0.98456)*

**=43.80375, -79.98456**
