Convert Coordinates in Seconds (No Setup Needed)The Simple Explanation
WGS84 (World Geodetic System 1984) is the default map datum for the entire world. It is the invisible 3D grid that GPS satellites use to calculate your position.
Real World Example
Unless you are using an old paper map that specifically requires a different datum (like NAD27 or OSGB36), you should ALWAYS leave your GPS set to WGS84.
Pro Tip
When entering coordinates into map apps, always double-check if there is a negative sign (-). Missing a negative sign on longitude will place you on the opposite side of the planet!
