Pat,
John is right. Usually 1 mm of rain is taken as 1 cm of snow, although
temperatrue and compression must be taken into consideration. There is also
a differnce between wet and dry snow.

SI, as a centimetre of snow is equivalent to a millimetre of rain. Snow
fall is measured in centimetres and rainfall in millimetres. Somehow the
scientist must have thought that 12 was close enough to 10 that to the
average person who couldn't care less, it was close enough. Like hitting
the broad side of the barn.
