How to Convert Angle to Decimal Degrees

Decimal degrees are a standard way to represent angles as a single number, where degrees, minutes, and seconds are combined into one value. This format is commonly used in GPS coordinates, surveying, and scientific calculations.

Steps to Convert Angle to Decimal Degrees

1. Identify the degrees, minutes, and seconds components of the angle.
2. Convert the minutes to a decimal by dividing by 60.
3. Convert the seconds to a decimal by dividing by 3600.
4. Add all three components together to get the decimal degrees.
