How to Convert UTM to Plus Code: Step by Step

  1. 1 Apply inverse UTM-to-latlong projection to get Decimal Degrees.
  2. 2 Normalize lat (+90) and lng (+180).
  3. 3 Encode 4 pairs of (lat, lng) index characters using OLC alphabet.
  4. 4 Encode 2 grid characters for the final precision.
  5. 5 Insert "+" at position 8.

Worked Example

Input 10T 550254 5272543

Latitude conversion:

Inverse UTM → 47.6062°N

Longitude conversion:

-122.3321°W → 84VRCWCV+GF

Result:

84VRCWCV+GF

Why Convert UTM to Plus Code?

Plus Codes are easier to communicate verbally and share via text than UTM coordinates.

Common Mistakes to Avoid

  • Skipping the intermediate DD step
  • Not normalizing coordinates before encoding
