180deg/3 = 60 deg

I need a formula for rad to deg.

Ananth said: (Sep 21, 2011)  
I need formula for the converting to radians into degrees.

Selva said: (Oct 13, 2011)  
I told you ananth.

1 deg=pi/180 rad, 1 rad=180/pi deg here given as pi/3 radians.

So 1 rad=180/pi deg,then pi/3 rad=(180/pi)*(pi/3) which results in 180/3=60degree.

Now its clear ma anand..

Degree=radians*180/pi.

For converting degree to rad multiply by pi/180 eg 60 deg=60*pi/180.
And for rad to degree multiply by 180/pi.

pi radians= 180 degree.

So pi/3 = 180/3 = 60 degree.

pi = 180 degree.

pi/3 rad = 180/3 = 60 degree.

Shan said: (Nov 22, 2015)  
1 degree = 180/pi.

pi/3 = pi/3*180/pi.

So pi/3 rad = 60 degree.

First of all we have to keep in mind that:

180 degrees = Pi Radians.

So, Pi/3 radians X (180 degrees/Pi radians).

It simplifies to: 180/3 radians.

= 60 degrees.

180°/3=60°.

1 rad = 57.3°.

π/3 rad = (π/3) x 57.3°.
= (3.142/3) x 57.3°.
= 60°.
