A gallon of soil weighs about 9 to 12 pounds. The weight will vary depending on the type of soil and how much moisture it contains.
One gallon of soil weighs about 8.5 pounds. This number will fluctuate depending on the type of soil and how much moisture it contains. For example, sand is much lighter than clay, so a gallon of sand will weigh less than a gallon of clay.
And if the soil is wet, it will weigh more than if it’s dry.
How Much Does a Gallon of Water Weigh

How Do I Measure a Gallon of Soil?
When it comes to measuring a gallon of soil, the most important thing to remember is that there are different types of soil. For example, sand is going to be much heavier than topsoil. This means that you can’t simply use a one-size-fits-all approach when measuring your soil.
The best way to measure a gallon of soil is by using a scale. This will allow you to get an accurate measurement, no matter what type of soil you’re dealing with.
To measure a gallon of soil using a scale, first find out how much your particular type of soil weighs per cubic foot.
You can do this by doing some research or contacting your local nursery or garden center. Once you know the weight per cubic foot, multiply that number by 0.1337 (this is how many cubic feet are in a gallon). This will give you the total weight of your gallon of soil in pounds.
From there, simply divide that number by 16 (there are 16 ounces in a pound) to determine how many ounces your gallon of soil weighs.
For example, let’s say that our type of soil weighs 100 pounds per cubic foot. We would then multiply 100 by 0.1337 to get 13.37 pounds for our total weight.
Dividing 13.37 by 16 would give us 0.835 ounces as our final answer – meaning that our gallon of soil weighs just over 8 and 1/3rd ounces!
Remember, these numbers will vary depending on the type of soil you’re using, so be sure to do your research before trying this method out yourself!
How Many Cubic Feet of Soil are in a 5 Gallon Bucket?
Assuming that a 5 gallon bucket is completely filled with soil, the answer would be approximately .71 cubic feet. This is because a gallon is equal to 128 fluid ounces, and 1 cubic foot is equal to 1728 inches. Dividing 128 by 1728 gives you .0737; thus, 5 gallons would be about .71 cubic feet.
