Degrees Minutes & Seconds
360° in a circle
1° = 1/360 of a circle
1’ = 1/60 of one degree
1” = 1/60 of one minute
1° = 60 minutes or 3600 seconds
Adding DMS
• Examples 25° 22’ 15”+ 60° 15’ 49” 85° 37’ 64” or 85° 38’ 04”
55° 55’ 43” + 67° 43’ 29” 122° 98’ 72” or 123° 39’ 12”
Subtracting DMS
• Examples 125° 43’ 32” - 44° 11’ 22” 81° 32’ 10”
235° 10’ 37” or 234° 69’ 97” - 140° 59’ 59” - 140° 59’ 59” 94° 10’ 38”
Converting DMS to Decimal
94° 30’ 30”
30”/60 = .5’ add to minutes
30.5/60 = .5083°
94° 30’ 30” = 94.5083°
