Conversions

The following functions provide useful conversions:

  • converts an angle measured in radians to degrees.
  • converts an angle measured in degrees to radians.
  • converts the polar coordinate (r, theta) into the rectangular coordinate (x, y). Theta should be expressed in units corresponding to the current angular mode.
  • converts the rectangular coordinate (x, y) into the polar coordinate (r, theta). Theta is returned in units corresponding to the current angular mode.
  • converts a number from a decimal-fraction (H.h) to minutes-second (H.MMSSs) format. This is useful for time expressed in hours and angles expressed in degrees.
  • converts a number in minutes-second format to decimal-fraction format. All of the calculator's functions (except this one) require numbers to be in decimal-fraction format.

For example,

  1. Press to convert pi to 180 degrees.
  2. Press to convert 360 degrees to 2 pi radians.
  3. Press (in RPN mode, use ) to convert the rectangular coordinate (x = 1, y = 2) to the polar coordinate (magnitude = 2.2361, angle = 63.4349 degrees). (Press button to view theta.)
  4. Press to convert 2.5 hours to 2 hours 30 minutes (2.30000 or 2"30'00.0).
  5. Press to convert 4 hours 23 minutes 48 seconds to 4.3967 hours.
