[ijabbott]

The German fx-991DE X seem to have many more unit conversions compared to the "international" EX model. It has 14 extra (26) length conversions, 12 extra (14) area conversions, 16 extra (20) volume conversions, 2 angle conversions ("rad -> r" and "r -> rad" - I don't know what those are!), 8 extra (12) mass conversions, 8 time conversions, 6 speed conversions, 2 acceleration conversions ("Gal -> m/s^2" and "m/s^2 -> Gal" - whatever Gal means!), 2 torque conversions, 6 force conversions, 10 extra (18) pressure conversions, 12 extra (16) energy conversions, 2 heat flow conversions ("Btu/min -> W" and "W -> Btu/min" - I guess these can be considered as 2 extra power conversions, but they are in a separate submenu), 2 specific heat capacity conversions, 2 viscosity conversions, 2 kinematic viscosity conversions, 8 magnetism-related conversions, 4 light-related conversions, and 8 radioactivity-related conversions.
