Angular values are converted from DEG to RAD to GRAD with each push of the DRG key.This function is used when doing calculations related to trigonometric functions or coordinate geometry conversions.

D egrees (D E G is shown at the top of the display)

Acommonly used unit of measure for angles.The angular measure of a circle is expressed as 360°.

R adians (R A D is shown at the top of the display)

Radians are different than degrees and express angles based on the circumfer- ence of a circle. 180° is equivalent to π radians.Therefore, the angular mea- sure of a circle is 2π radians.

G r ads (G R A D is shown at the top of the display)

Grads are a unit of angular measure used in Europe, particularly in France. An angle of 90 degrees is equivalent to 100 grads.

The relationships between the three types of angular units can be expressed as right:

90° (DEG) = π/2 (RAD) =

100 (GRAD) =
