DMS to Decimal Degrees Converter
Combine degrees, minutes and seconds with a hemisphere letter into signed decimal degrees.
Description
Combine degrees, minutes, seconds, and hemisphere into one signed decimal coordinate.
DMS to Decimal Degrees Converter combine degrees, minutes, seconds, and hemisphere into one signed decimal coordinate.
Use this to normalize coordinates copied from navigation, surveying, or geographic records before mapping, distance, or spatial encoding work.
When to use DMS to Decimal Degrees Converter
Use this to normalize coordinates copied from navigation, surveying, or geographic records before mapping, distance, or spatial encoding work.
How it works
Decimal degrees equal the absolute degree value plus minutes divided by 60 plus seconds divided by 3600; S and W produce negative results.
Interpreting the result
Keep the input units, direction conventions, encoding, and ordering rules visible when reusing the result. Preserve the full returned value for downstream calculations and round only for presentation.
Assumptions and limitations
Minutes must be below 60, seconds below 60, and degree limits depend on whether the hemisphere is latitude or longitude. Avoid mixing a negative degree sign with a contradictory hemisphere.
