How much water does it take to make an inch of snow?

If it’s average snow, not too wet, not too dry, you’d need about a tenth of an inch of water to make an inch of snow.

The general rule is that one inch of water produces ten inches of average snow. But that’s the average.

An inch of water would make about fifteen inches of dry and fluffy snow, but only five or six inches of wet and soggy snow.
