What does dms mean on calculator?

DMS on a calculator stands for Degrees, Minutes, and Seconds, which is a way to express angles in a sexagesimal system. In this format, an angle is represented as degrees (°), minutes ('), and seconds ("). For example, 45° 30' 15" indicates 45 degrees, 30 minutes, and 15 seconds. Many scientific and graphing calculators have a DMS mode to facilitate conversions between decimal degrees and DMS format.
