How to Convert Plus Code to DD: Step by Step

  1. 1 Remove the "+" separator from the code.
  2. 2 Process character pairs: each pair = (latitude char, longitude char).
  3. 3 Pair 1 resolution: 20°. Pair 2: 1°. Pair 3: 0.05°. Pair 4: 0.0025°.
  4. 4 For characters after the separator: decode as 5×4 grid subdivisions.
  5. 5 The resulting latitude and longitude range midpoints are the coordinates.

Worked Example

Input 8FW4V75V+8Q

Latitude conversion:

Pairs: 8F→(6,9) WV→(18,17) 45→(17,3) V5→(3,17) Grid: 8Q→(1,2,3,3)

Longitude conversion:

Midpoints → 48.8584°N, 2.2945°E

Result:

48.858400, 2.294500

Common Mistakes to Avoid

  • Not removing the separator before processing
  • Confusing short codes (which need a locality context) with full codes
  • Using wrong resolution for each code pair
