Group 1 -> linear, area, volume and weight.
Group 2 -> speed, pressure and temperature.

- to do conversions, among units from the same family, just enter with the first unit value, by using the numeric keypad, tap the actual unit key, identified by the unit label on the key, and after that, tap the target unit key.
