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°
The following procedure assumes that the calculator’s
default angle unit is degrees.
