How it works
Every field reads its own format and recognises the others if you paste them there. Conversions use the WGS 84 ellipsoid and the same formulas as the CoyoCam stamp, so a position reads the same here as on a photograph: decimal degrees to six places (about 10 cm), seconds to two decimals, UTM to the metre with the latitude band letter, and MGRS to 1 m. UTM and MGRS cover 80°S to 84°N, including the Norway and Svalbard zone exceptions; beyond that the poles use another grid.
Questions
Which DMS formats can I type?
Most of the usual ones: 48°30'48.16"N 32°16'25.10"E, N 48° 30.802' E 32° 16.418', 48 30 48 N 32 16 25 E, or with minus signs instead of S and W.
What does the letter in a UTM coordinate mean?
It is the latitude band, C to X (without I and O), each 8° tall; N and the letters after it are in the northern hemisphere. Some write a plain N or S for the hemisphere instead — here the letter is always read as the band, as GPS receivers and the app write it.
Why does an MGRS reference convert to a point slightly off?
An MGRS reference names a square, not a point: 10 digits mean 1 m, 8 digits 10 m, 6 digits 100 m. The converter gives the square's centre.
