Quick Answer: How many inches of snow equals an inch of water?

How much water is 12 inches of snow?

Commonly, the percentage of water to snow is called the “snow ratio”. An old rule of thumb was that for every 10 inches of snow, there would be 1 inch of water (10:1). However, this is far from the norm, and recent studies indicate that a 12:1 ratio might be more representative (on average) for the Upper Midwest.

How many inches of water are in a foot of snow?

The quick answer: sometimes. When the temperature is around 30 degrees, one inch of liquid precipitation would fall as 10 inches of snow — assuming the storm is all snow. But the amount of moisture in each snowflake differs depending on the temperature. That’s the variable that changes the snow-to-rain ratio.

How much snow equals a gallon of water?

One gallon (US measure) of water weighs approximately 8.3 pounds. If the snow in your one gallon container weighs four pounds then the water content of the snow is almost 50 percent which means it will take two gallons of snow to make one gallon of water.

How do you measure water content in snow?

This measurement is made by melting the snow that has fallen in the precipitation gauge and measuring the liquid as is done for rainfall. Water content also can be measured by taking a core sample of the snowfall from the SMB or other measurement surface.

How much snow is 4 inches of rain equal to?

So, at 3 °F, 4 inches of rain is equivalent to 160 inches of snow.

How much is 0.1 inches of snow?

In summary, 0.1 inch of water can yield as little as 0.4 inch of snow or as much as five inches of snow under extreme conditions. More commonly, 0.1 inch of water yields from 0.6 to 1.1 inches of snow.

How much water is in 8 in of snow?

More densely packed and wet snow is in the ratio of 8 inches of snow to 1 inch of equivalent rainfall, and more powdery snow is about 14 to 1 ratio. Obviously this is an approximation but a good one.

How much water is in snow when it melts?

Using a rule of thumb that each 10 inches of snow, if melted, would produce one inch of water, then each inch of snow produces about 2,715 gallons of water per acre.
