Convert to degrees and radians

Question

Occasionally you may encounter an angle that’s given in the degrees/minutes/second form. A degree is divided into 60 minutes (or minutes of degree), and a minute (of degree) is divided into 60 seconds.

Let a= 66 degrees 31' 24''.

Then a=  degrees (in decimal notation) and

a=   radians.

Answer 1

a = 66 + (31 / 60) + (24 / 3600) degrees, this is simple calculator stuff!

radians = aπ / 180, againm simple calculator stuff
