Coordinates converter: decimal, DMS, UTM and plus codes
Paste coordinates in any format and see the others instantly. Below: how each format reads, and the common mistakes with land coordinates in Thailand.
- Decimal (latitude, longitude)
—- Degrees, minutes, seconds (DMS)
—- UTM (WGS84)
—- Plus code

Coordinates on older documents may use the Indian 1975 datum, which can differ from WGS84 by hundreds of metres. Always check the spot on the map.

Decimal coordinates are written latitude, longitude, e.g. 13.756306, 100.501806. In Thailand latitude is about 5.6–20.5 and longitude about 97.3–105.7. If the first number is above 90, the order is probably swapped; swap it back and check the map.
Formats
| Format | Example (same point) |
|---|---|
| Decimal degrees | 13.756306, 100.501806 |
| DMS | 13°45'22.7"N 100°30'06.5"E |
| UTM (WGS84) | Zone 47N, E 662367, N 1521281 (approx.) |
| Plus code | 7P52QG42+GP, or short QG42+GP Bangkok |
DMS to decimal: degrees + minutes ÷ 60 + seconds ÷ 3,600. UTM gives metres east and north. Thailand spans zone 47N (west of 102°E) and zone 48N (east of 102°E); always state the zone. A short plus code needs a locality after it.
Datum: Indian 1975 vs WGS84
GPS and Google Maps use WGS84, but many older Thai maps and survey documents use Indian 1975. The same UTM numbers on different datums can be a few hundred metres apart. Ask which datum your X/Y values use, and always confirm the location on the map.
