What is the weight of cubic meter of snow?

Answer 1

It varies, but we can make an estimate based on the weight of water and how much water is contained in 'fresh fall' snow.

Water weighs 1000Kg per cubic meter (at 4 degrees Celsius), and 'fresh fall' snow melted to water becomes approximately 1/10th its original volume. So, we can estimate that a cubic meter of snow weighs about 1/10th that of water = 100Kg.

However, snow is just elaborate ice crystals, and so these will change form many times depending on temperature and time, so a cubic meter of snow may become heavier as time passes due to compacting ice crystals.

Still, it pays to knock all the snow and ice off your car, as it will always contain some sort of weight, and will reduce fuel economy because of this.
