# Snow density

### From Fiswiki

**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**.]
