The cited overview of Data conversion supplies background for the terminology and domain context used by this tool.^[1]

Combine degrees, minutes and seconds with a hemisphere letter into signed decimal degrees. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.

Decimal degrees

Returned number. Signed decimal degrees.

• Unicode normalization, locale, grapheme clusters, malformed input, ambiguous syntax, and implementation-specific conventions can change text-processing results.
• Minutes must be at least 0.
• Minutes must be no greater than 59.
• Seconds must be at least 0.
• Seconds must be no greater than 59.999999.
• Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.

Preserve the original text, test representative non-ASCII and malformed cases, and use a standards-aware parser or serializer when interoperability matters.
