Dielectric constant (ε r) For dry snow density 0.1 to 0.9 g/cm 3: 1–3.2: ... Engineers design for such loads, which are measured in kg/m (lb/ft) and power ...
The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
Snow density (ρ s) is the mass per unit volume of snow of a known volume, calculated as kg/m 3. Classification runs from very fine at below 0.2 mm to very coarse (2.0–5.0 mm) and beyond. Snow hardness (R) is the resistance to penetration of an object into snow. Most snow studies use a fist or fingers for softer snows (very soft through ...
The weight of snow can vary dramatically: A cubic foot of dry, powdery snow might weigh as little as three pounds, while a cubic foot of heavy, wet snow can weigh as much as 10 pounds.

It uses the following characteristics (with units) to describe deposited snow: microstructure, grain shape, grain size (mm), snow density (kg/m 3), snow hardness, liquid water content, snow temperature (°C), impurities (mass fraction), and layer thickness (cm). The grain shape is further characterized, using the following categories (with code ...
It is ice that is at an intermediate stage between snow and glacial ice. [1] Firn has the appearance of wet sugar, but has a hardness that makes it extremely resistant to shovelling. Its density generally ranges from 0.35 g/cm 3 to 0.9 g/cm 3, [1] [2] and it can often be found underneath the snow that accumulates at the head of a glacier.
