k Converting an Input Value to the

Calculator's Default Angle Unit

After inputting a value, press 1G(DRG ) to display

the angle unit specification menu shown below. Press the

number key that corresponds to the angle unit of the input

value. The calculator will automatically convert it to the

calculator's default angle unit.

Example 1: To convert the following values to degrees:

  radians = 90 , 50 grads = 45 

2

The following procedure assumes that the calculator's

default angle unit is degrees.
