Snow detail

last night I entered 1.25" snow in input daily weather. Today I checked snow detail graphed and its shows 31.8 cm. Thats not the correct conversion. The correct conversion should be 3.175cm. It also shows up wrong in the wind chart 3-d graph.

Is it possible to have a button to click to have the option to convert the cm to inches on the snow fall chart?

Thanks
