How it's calculated

Formula

D=⌊∣decimal∣⌋,M=⌊(∣decimal∣−D)×60⌋,S=((∣decimal∣−D)×60−M)×60D = \lfloor |decimal| \rfloor, \quad M = \lfloor (|decimal| - D) \times 60 \rfloor, \quad S = ((|decimal|-D)\times 60 - M) \times 60
D, M, S
— Degrees, minutes, seconds

What is the Decimal Degrees to DMS Calculator?

This is the inverse of DMS-to-decimal conversion — it peels off the whole-degree part, then converts the fractional remainder into minutes and seconds.

How to use it

  1. 1 Enter a coordinate in decimal degrees.

Limitations

  • •For negative (southern/western) coordinates, the sign applies to the whole degrees value — minutes and seconds are always shown as positive magnitudes, matching standard DMS notation.

Frequently asked questions

Why do minutes and seconds never show a negative sign?

By convention, DMS notation keeps minutes and seconds as positive magnitudes and puts the direction (or a single negative sign on degrees) to indicate hemisphere.
