I guess you talk about precipitation units in meteograms .
When there is no unit shown with the amount value, it is rain in mm or inches (according to your setting).
When you get CM or IN (according to your setting) next to the amount value, it means it is snow.
You can check it with the icons shown above temperature and the blue color of figures are different. Dark blue for rain et light blue for snow.
Here with cm of snow and mm of rain.

So there is no reason to stop showing precipitation units because they are really useful to know if rain or snow is forecast. I cannot imagine you get snow all the year round.
