Conversion Formula:
| From: | To: |
Angle degree conversion transforms angular measurements from degrees and minutes format to decimal degrees format. This conversion is essential for mathematical calculations, GPS coordinates, and various scientific applications where precise angular measurements are required.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 degree equals 60 minutes, we convert minutes to decimal by dividing by 60 and add this to the whole degrees.
Details: Decimal degrees are widely used in digital mapping, GPS systems, geographic information systems (GIS), and mathematical calculations because they are easier to work with in computational operations compared to the degrees-minutes format.
Tips: Enter whole degrees as an integer (0 or positive), and minutes as an integer between 0-59. The calculator will automatically compute the decimal degree equivalent with high precision.
Q1: What is the difference between degrees-minutes and decimal degrees?
A: Degrees-minutes format uses whole degrees and minutes (1°30'), while decimal degrees combines them into a single decimal number (1.5°).
Q2: Can I convert decimal degrees back to degrees and minutes?
A: Yes, the whole number part becomes degrees, and the decimal part multiplied by 60 becomes minutes.
Q3: What about seconds in angular measurements?
A: For more precise conversions including seconds, you would use: Decimal Degrees = Degrees + Minutes/60 + Seconds/3600.
Q4: Where is this conversion commonly used?
A: GPS coordinates, navigation systems, astronomy, surveying, and any application requiring precise angular measurements.
Q5: What is the maximum precision of this calculator?
A: The calculator provides results with 6 decimal places, which is sufficient for most practical applications including detailed mapping.
