Convert Coordinates in Seconds (No Setup Needed)The Simple Explanation
Geocaching traditionally uses the Degrees and Decimal Minutes (DDM) format (e.g., N 45 12.345'). Most modern map apps expect Decimal Degrees (DD).
Real World Example
If you try to paste N 45 12.345' into Apple Maps, it might fail. You need to convert it to 45.20575 first to find the cache.
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!
