Angle unit Conversion
The calculator angle unit setting is“Degree, pressing Shift SET-UP enter
the setup menu to change the unit to“Radian“or“Gradient:
1:Maths 2:Line
3:Deg 4:Rad
5:Gra 6:Fix
7:Sci 8:Norm
Press the corresponding number key 3 , 4 or 5 for the angle unit you need then
the display will show the D , R , G indicator accordingly.
Convert an angle unit between“Degree，“Radian and“Gradient”by
pressing Shift DRG► .
1:° 2：r
3:’
Then, pressing 1 , 2 or 3 will convert the displayed value into the selected
Angle unit.
