How can I convert a radian angle to a degree one and add ° after it?

I am using N[(Pi/4)/Degree], but the output is 45. with the point.

How can I have instead 45°?

• perhaps Pi/4/. Pi -> 180 Degree – happy fish May 29 '17 at 9:45
• I've edited the answer and reopened this question as I believe it will benefit future readers. That is subjective but there are precedents like this, I'm open to discussion. – Kuba May 30 '17 at 6:37

(Pi/4) * (180 Degree /Pi)

Degree is a symbol similar to Pi, it contains a value Pi / 180 and it keeps the symbolic form unless used with finite precision numbers.
All functions in Mathematica work with radians so this symbol is a convenient form of a scaling factor: 40 Degree is verbose but holds numerical value in radians.
Extracting radians is a simple as taking N[40 Degree], or using 40..
