Frequently Asked Questions

What is the difference between Decimal Degrees, DMS, and UTM?

Decimal Degrees (e.g. 48.8584, 2.2945) express latitude/longitude as a single decimal number. DMS (Degrees, Minutes, Seconds) is the traditional format (e.g. 48°51'30.2"N) used on paper maps and GPS units. UTM (Universal Transverse Mercator) is a projected coordinate system that expresses position as a zone number plus easting/northing in meters, useful for measuring distance and area.

What datum does this converter use?

All conversions use WGS84, the datum used by GPS and virtually all modern web maps.

How do I enter DMS coordinates?

Type the degrees, minutes, seconds, and hemisphere letter in any common layout, such as 48°51'30.2"N, 48 51 30.2 N, or 48d51m30.2sN. A leading minus sign is treated the same as a South/West hemisphere letter.

Is my data private?

Yes, completely. All conversion happens inside your browser using JavaScript. Nothing is sent to a server.
