What is the formula to convert 1 square yard of snow to gallons of water?

Question

I would like to know what the volume of 1 square yard of snow 2 inches deep to gallons of water.

Answer 1

1 square yard = 36 x 36 = 1296 sq.in.
2 inches deep
1296 x 2 = 2592 cubic in.

snow to liquid: 259.2 cubic in.
This is for fresh new snow, without being packed down.

1 gallon = 231 cu.in.
259.2 / 231 = 1.122 gallons

Answer 2

There is no answer. 1 square yard is an area. 1 gallon is a volume. You need to know the depth of the snow and how well it is compacted.

Answer 3

Of course this depends on how packed is the snow... but the convention for meteoroligists is a 10:1 conversion ratio, i.e. 2 inches converst to 0.2 inches of water.

Convert everything to feet, your volume is
0.2/12 * 3 * 3 = 0.15 cubic foot of water... convert to gallons as directed.

Answer 4

On average it takes about 3 inches of snow to make 1 inch of water. So if the conversion holds true it should be about 3 gallons of snow to make one gallon of water. Although it will vary depending on the consitancy of the snow.

Answer 5

there are 12*3 inches in a yard so there are 36^2 inches in one square yard.

Volume of a prism = Cross sectional Area x Length

so

V=36^2 * 2 = 2592inches^3

Then convert from inches cubed to gallons

Answer 6

I use to remember a rule of thumb about this from watching the weather as a kid.

Check the link out below. The answers you have are correct, but you can at least get an idea with this.

Hope this helps.

Answer 7

The only answer is to MELT THE SNOW and then you can measure volume

Answer 8

there is no formula........ 1 yard of snow can be packed differently.... therefore you cannot figure how much water is in it without melting it 1st......the equasion would be idfferent every time..

Answer 9

what is the variable of density of the snow? Packed or loose? Dirty or clean?

Answer 10

Come to my backyard & dig it up & watch it melt.
