How to convert degrees minutes and seconds into decimal form?

Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600)

  1. First, convert minutes and seconds to their degree equivalents and add the results. 25’/60 = 0.4167° 30″/3600 = .0083°
  2. Then, add this number to the number of degrees. 39° + 0.425° = 39.425°
  3. So, the final result is: 39° 25′ 30″ = 39.425°

How do you round decimals to the nearest degree?

Rounding values expressed in degrees and minutes is similar to rounding decimals. However, because there are 60 minutes in a degree, the half way point is 30: If the number of minutes is less than 30, we round down to the nearest degree. If the number of minutes is 30 or more, we round up to the nearest degree.

How are decimal degrees calculated?

Here’s How to Do the Conversion



The whole units of degrees will remain the same (e.g., if your figure is 121.135 degrees longitude, start with 121 degrees). Multiply the decimal portion of the figure by 60 (e.g., . 135 * 60 = 8.1).
