Snow Density: The amount of space between molecules or particles of any substance is what determines its density. Density is equal to the mass (or weight) of a substance divided by its volume (d=m/V).

The metric system was set up in such a way so that the density of water can be written as 1 gram per milliliter (1g/mL). One mililiter (mL) is also equal to one cubic centimeter.

'Water' is "pure precipitation."

Snow, on the other hand, is mostly air. The density of snow is related to the measure of the water in snow.

The density of snow might be expressed as water per cubic millimeter of snow or 100 mL/L [density=V(water)/V(snow), where V=volume.]

Material Density (kg/m-3)
Sea Water 1030
Fresh water 1000
Ice 920
Snow 100-500
Air 1.29
Steam(100oC) 0.6

(values quoted at standard room temperature. and pressure)
