Convert from DMS to Radians
1) 61degree 24'
2) 75degree 30'
Convert from Radians to Degress
1) 2
2) 1.3
Please help how to solve and calculate it in calculator. I got confused. :( :)

180 degrees = pi radians, so
61°24' = (61+24/60)*pi/180 = 1.07 radians
going the other way,
1.3 radians = 1.3 * 180/pi = 74.4845° = 74°29.07' = 74°29'4.2"
