DMS & Angle Conversion
Convert accurately between decimal degrees, degrees-minutes-seconds (DMS), radians and surveying quadrant bearings.
Convert an Angle
Enter one angle and choose its unit. The calculator returns the equivalent decimal degrees, DMS and radians.
For DD.MMSS input, use degrees, minutes and seconds as two-digit fields after the decimal. Example: 45° 30′ 15″ → 45.3015. Negative angles are supported.
Enter an angle to see its equivalent forms.
Degrees–Minutes–Seconds
Enter degrees, minutes and seconds separately. Minutes and seconds must be from 0 to less than 60.
Use the sign on the degrees field for a negative angle. Minutes and seconds should normally be entered as positive values.
Enter degrees, minutes and seconds.
Angle Conversion Reference
Formulas and input conventions used by this calculator.
Degrees → radiansrad = degrees × π / 180
Radians → degreesdegrees = rad × 180 / π
DMS → decimalD + M/60 + S/3600
Decimal → DMSD = integer part; M and S are successive remainders
Survey note: Angular units and sign conventions matter. For bearings, use the bearing calculator for quadrant/whole-circle bearing workflows. This calculator is intended for precise angle-unit conversion.
