My GPS/phone is giving me latitude/longitude in the wrong format; how do I change it to decimal degrees?

The latitude/longitude units can usually be changed in the general settings of the GPS and on many phone apps. Look for the format for decimal degrees (DDD.DDDDD). If this is not an option, record the latitudes/longitudes in the format provided and convert to decimal degrees at a later time. Here is a suggested online tool to convert between units.
