The Degrees and Minutes Calculator converts angle measurements from degrees-minutes-seconds (DMS) format to decimal degrees (DD) format. This is commonly used in geography, astronomy, and navigation.
The calculator uses the following conversion formula:
Where:
Explanation: Since 1 degree = 60 minutes and 1 minute = 60 seconds, we divide minutes by 60 and seconds by 3600 to convert them to degrees.
Details: Decimal degrees are easier to use in calculations and computer systems, while DMS format is more human-readable and traditional in many fields.
Tips: Enter whole degrees, minutes (0-59), and optional seconds (0-59). All values must be valid numbers within their specified ranges.
Q1: Why convert to decimal degrees?
A: Decimal degrees are easier to use in mathematical calculations and are the preferred format for most digital mapping systems.
Q2: How precise is this conversion?
A: The calculator provides results with 6 decimal places, which is precise enough for most practical applications.
Q3: Can I convert negative angles?
A: Yes, for southern latitudes or western longitudes, simply enter negative degrees (minutes and seconds should remain positive).
Q4: What's the difference between minutes of angle and nautical miles?
A: While 1 minute of latitude equals 1 nautical mile, this calculator deals with angle measurement conversion, not distance.
Q5: How do I convert back to DMS format?
A: Multiply the decimal portion by 60 to get minutes, then multiply the new decimal portion by 60 to get seconds.
