Why does 1 inch of rain equal 10 inches of snow?

646 views

Is this conversion even right? I found it on google with little explanation. One inch of rain seems minuscule to 10 inches of snow but maybe I have a fundamental misunderstanding of how much one inch of rain actually is. Please help.

It is difficult to predict how much snow you will get because you have to predict how much water will fall AND how fluffy the snow will be. Snow can be 2x to 15x as fluffy as plain liquid water, so forecasters just predict the amount of water and then multiply by 10.
