Five-gallon buckets are a versatile and essential item for any project. It’s important to note that a five-gallon bucket has a capacity of 0.67 cubic feet, which is particularly useful when transporting cement. Whether you’re carrying supplies, paint, or cement, understanding the capacity of a five-gallon bucket is essential.
The five-gallon bucket is likely the most frequently used container in both homes and gardens. Constructed from industrial-grade plastic, it is a robust utility pail that is resistant to cracking.
A five-gallon bucket is a versatile tool that can be used for a wide range of purposes such as carrying paint, cement, parts, topsoil, and other items required for house or yard work. However, if you are working in construction or any home improvement project, it is important to know the volume capacity of a five-gallon bucket.
To determine the volume of a five-gallon bucket, it is necessary to measure its dimensions and calculate its volume based on its unique shape. This is because a bucket is not a perfect cube, and therefore, a simple conversion from gallons to cubic feet is not accurate.
A 5-gallon bucket has a volume of 0.67 cubic feet, which is also equivalent to 1,155 cubic inches. In comparison, a 1-gallon bucket has a volume of 0.134 cubic feet. It’s important to note that not all 5-gallon buckets have the same volume, as some may have a volume of 0.98 cubic feet.
What is a Cubic Foot?
A cubic foot is a unit of measurement used to describe the volume of a space or object. It is defined as the volume of a cube that measures one foot on each side. Knowing the cubic footage of a space or object is useful in determining how much it can hold or how much material is needed to fill it.
Calculating the cubic feet of a five-gallon bucket can be a bit more complicated due to its truncated cone shape. To calculate the volume, you’ll need to measure the diameter of the bucket’s top and bottom circles, as well as its height. Then, you can use the formula for the volume of a truncated cone to determine the cubic feet.
Dimensions of a Five-Gallon Bucket
To calculate the cubic feet of a five-gallon bucket, you will need to have two measurements: the height of the bucket and the radius of the bucket.
The measurements for a five-gallon bucket can vary depending on the brand, but the image provided above can serve as a reference for standard measurements.

For the sake of simplicity, let’s round up some measurements. Typically, the height of a five-gallon bucket is approximately 15 inches. To determine the radius, divide the diameter by two, giving you a radius of around 6 inches.
radius = diameter ÷ 2
radius = 12 ÷ 2
radius = 6 inches
How to Calculate Cubic Feet in a Five-Gallon Bucket
Yes, that’s correct. To calculate the cubic footage of a cylinder (such as a five-gallon bucket), you use the formula:
volume = π × r2 × h
where π (pi) is a mathematical constant approximately equal to 3.14.
The volume of a cylinder in cubic feet is equal to π times the radius in feet squared times the height in feet.
Keep in mind that, π is roughly equal to 3.14159265359.
To solve for the cubic footage of a five-gallon bucket, we first need to convert the measurements to feet. The height of 15 inches is equal to 1.25 feet, and the radius of 6 inches is equal to 0.5 feet.
volume = π × 62 × 15
volume = 3.14159265359 × 36 × 15
volume = 1695.6 cu inches
To convert the cubic inches to cubic feet, we need to divide the cubic inches by 1728, which is the number of cubic inches in a cubic foot.
Using the previous calculation, we know that the volume of a five-gallon bucket is 11550 cubic inches.
So, to convert this to cubic feet, we divide 11550 by 1728, which gives us approximately 0.67 cubic feet.
Therefore, the volume of a standard five-gallon bucket is approximately 0.67 cubic feet.
1 cubic foot = 1728 cubic inches
1695.6 cu inches ÷ 1728 cu inches
volume of a five-gallon bucket = 0.98 cu feet
Five-Gallon Bucket Use Ideas
- The five-gallon bucket is an extremely adaptable tool with a multitude of applications, made even more attractive by its affordability. There is an extensive list of possible uses for this item, including both traditional and unconventional options. Here are a few examples of some of the more typical and less common ways to utilize a five-gallon bucket:
- For composting in the kitchen, using a five-gallon bucket with a lid can be helpful in trapping the smell and facilitating transportation.
- Provided that the buckets are food-grade, they can be utilized for bulk food storage, including items such as pasta, rice, flour, and other grains.
- By cutting a hole in the bottom of the bucket, hanging it against a fence, and filling it with growing medium, you can grow tomatoes upside-down, with the plant expanding outwards from the base.
- For yard or garden work, the five-gallon bucket can be employed to transport materials like soil, sand, and other necessary items.
- Marinating meat, poultry, or fish is also possible by using a food-grade bucket or a liner for a non-food-grade one. These uses are just the tip of the iceberg, as there are countless other ways to utilize a five-gallon bucket that can be easily found with a quick search online.

How do I calculate how much dirt I need?
To determine the quantity of soil required for your project, you must first determine the necessary volume. The process begins by obtaining the dimensions of the area that you intend to cover with soil, specifically the width and length. Multiply these two numbers to determine the area that needs coverage. Afterward, determine the depth or thickness of the layer of topsoil required for the project. Finally, calculate the volume by multiplying the topsoil’s thickness by the area calculated earlier. This final result represents the amount of soil required for the project.
How many gallons is 2 cubic feet of soil?
To determine the number of gallons contained within 2 cubic feet of soil, a straightforward conversion is required. Knowing that approximately 7.48051948 gallons are present within a single cubic foot, this value must be multiplied by the total cubic foot quantity to determine the number of gallons. Therefore, by multiplying 7.48051948 by 2, the result would be approximately 14.96 gallons contained within the 2 cubic feet of soil.
Wrapping it Up
Five-gallon buckets are probably the most prevalent type of container utilized around the home. In order to use them correctly, it’s essential to comprehend their volume and the quantity of material they can hold.
However, you cannot convert gallons to cubic feet directly to obtain the volume of a five-gallon bucket. By applying the formula for the volume of a cylinder, you can determine that a typical five-gallon bucket has a volume of 0.98 cubic feet.
