DMS stands for Degrees, Minutes, Seconds. One degree = 60 minutes, one minute = 60 seconds. It is the traditional way to express angular measurements and geographic coordinates.

Which format does GPS use?

GPS devices can use either decimal degrees or DMS. Decimal degrees (e.g., 40.7128) are simpler for calculations. DMS (40° 42' 46") is traditional for navigation. Most devices let you choose.
