How to convert 2.5 radian to degree/minute/second?
1) converting to degree : (Multiply by ##180/pi## ) ##=## 2.5 x ##180/pi## ##=## ##143.31^o##
2) converting to minutes :(0.31 X 60) ##=## 0.31 x 60## ##= 18.6'
3) converting into seconds : (0.6 X 60) ##=## 0.6x 60## ##= 36"
So , 2.5 radians ##=## ##143^o## 18'36"
