💡 Decimal degrees: longitude,latitude (e.g. 116.391231,39.907234)
💡 DMS: lon°min'sec"dir,lat°min'sec"dir (e.g. 116°23'28.43"E,39°54'26.04"N)
Guide, data sources & FAQ
What problem it solves
Bridges navigation formats: many instruments and paper maps use DMS while web maps and APIs prefer decimal degrees.
Data sources
Pure client-side trigonometric formatting for WGS84 angles. No map provider call is required for conversion itself.
Frequently asked questions
What is a valid DMS example?
Example: 37°46′29.6″N 122°25′09.3″W. Symbols and hemisphere letters must match the selected input style.
Do minutes and seconds wrap correctly?
Yes—minutes and seconds are constrained to their normal ranges during conversion. Out-of-range values are rejected or normalized per the tool rules.
Is DMS still WGS84?
Yes. DMS is only a display format for the same WGS84 latitude and longitude.
Can I batch convert many pairs?
Yes. Paste multiple lines and convert together, then copy all valid outputs.
