What Is The Density Of Snow?
Would you like to play with snow? Maybe yes. What will happen if the density of snow is high? Then no one like to play with snow becaue when you throw it on someone, they get hurt. Many people think that ice and snow are the same, but they are wrong. Both ice and snow are different from each other. How? So, snow is nothing but the frozen atmospheric vapor which falls in winter on earth as light flakes whereas ice is simply frozen water. In fact, ice and snow both are made up of water, but they are not the same and it is because of their densities. Who has more density or who has less density, will be cleared while reading this article. So, let’s get started and know the density of snow.
What Is The Density Of Snow?
The density of snow is 100 kg/m3. Now you may be thinking as it is the constant snow density. No, it is not constant because as time increases snow starts converting into the water, and hence its density increases. There is no need to describe what happens to the density of snow over time because you can understand it logically.

When you compare the density of snow vs water and the density of snow vs ice, in both cases snow density is smaller. Let’s know the snow density in other units also,
The density of snow in kg/m3 is 481 kg/m3, the density of snow g/cm3 is 0.48 g/cm3, the density of snow g/mL is 0.48 g/ml, and the density of snow in lb/in3 is 0.017 lb/in3.
Now you have a basic understanding of the density of snow in grams as well as the density of snow in g/ml. Let’s have a look at the definition of snow density.
Definition Of Density Of Snow
The density of snow is defined as the mass per unit volume of the snow or the amount of space occupied by the snow. Usually, the density is measured in kilograms per cubic meter but its SI unit is grams per centimeter cubed. The snow density changes too quickly because the snow starts melting as soon as falls on the earth’s surface. And also it change when you apply pressure on it, because it get convert into water. Let’s see the formula for snow density,
The density of snow = mass of snow/volume of snow g/cm3
Or
d = mv g/cm3
Where, d is the density of snow
m is the mass or weight of snow, and
v is the volume of snow.
How To Calculate Density Of Snow?
To measure the exact snow density go and collect some snow, but keep in mind not to pack it into your measuring cup. Because, packing more snow in a smaller volume will artificially increase its density. Therefore, be sure to record the volume of snow you collected. Let’s calculate the snow density,
- Go and collect some fresh snow.
- As soon as you collect it, measure its weight and note down it.
- If it is not possible, then there is a trick to measure the mass of snow. It is, let it melt the collected snow at room temperature because mass never changes, whether it is solid or liquid mass is the same.
- Now measure the mass of water, and you know the mass of water in 1ml whihc is equal to 1g. If your melted snow is 32 ml, its mass will be about 32 grams.
- Volume remains the same as the container used to collect the snow.
- Now divide the mass by volume, and you will get the snow density.
For example, if you have collected snow in a cylindrical container with a volume of 100 cm3 and the weight of collected snow is 48 grams. What will be the density of anow?
By using the density formula,
The density of snow = mass of snow/volume of snow g/cm3
= 48/100 = 0.48 g/cm3
So, the snow density is 0.48 g/cm3.

FAQ
What Is The Density Of Snow Compared To Water?
The density of water is 1000 kg/m^3 and snow density is usually measured as a ratio to this. So snow which is 100 kg/m^3 is specified as 100/1000, or 10 percent (of the density of water).
How Is Snow Density Measured?
Density for the snowpack is calculated by dividing the snow water equivalent by the depth of the snow. Density can be used to measure variability across the snowcourse and is also used to quality control the samples taken.
Is Snow Denser Than Ice?
The density of snow is less than that of crystalline ice. Snowflakes are composed of an arrangement of ice crystals, but snow that accumulates on the ground is a porous medium dominated by air pockets.
Does Fresh Snow Stick Together In A Ball?
Snow is basically ice crystals , and when you pack the crystals together, you need to apply enough pressure with your mitten-clad hands to get some of them to melt. When you remove pressure, the ice will re-freeze and glue the snow together in whatever shape you packed it in.
Which Is More Dense Snow Or Water?
SNOW WEIGHT AND DENSITY – Snow is less dense than water. A cubic foot of snow can weigh anywhere between 1 to 20 pounds per cubic foot, depending on moisture content. The actual water content of snow generally ranges from 5% to 32%. Snow density is a function of temperature, wind exposure, and time.
How Do You Calculate Snow Weight?
To calculate the weight of snow, you take 7.48 gallons of per cubic foot of water, which is about 62.4 pounds. You then divide it by the amount of snow (in inches). Light and fluffy snow weigh the least. If it snows 12” of light and fluffy snow, it will weigh about 5.2 pounds.
What Does 30 Lb Snow Load Mean?
The state’s building code requires residential roofs withstand snow loads of at least 30 pounds per square foot. That type of load, says Town of Suffield Building Official Ted Flanders, takes 4 feet of fluffy snow, 2 feet of dense snow or about six inches of water.

Conclusion
After reading this article you come to know different facts about the snow density as well as how to find the snow density. Snow density calculation is very easy but it get complex because of melting snow. As it changes quickly, therefore, you will see different snow densities every time when you measure it. So, the average snow density is 100 kg/m3. Now, you have learned all about the density of snow.
