Despite resembling a typical scientific calculator in appearance, such as those by competitors Casio and Sharp, the 9g departs from HP calculator tradition because it does not have an RPN mode. It is also particular unusual for its display, which includes a compact dot-matrix grid for displaying graphs, a dot-matrix character line which displays expressions being input (acting as a continuation of the dot-matrix grid), and a seven-segment line to display answers to expressions.

The HP-9g is similar to Citizen SRP-325G, also designed by Kinpo Electronics, Inc.
