A cubic feet calculator is used to calculate the volume of a cube-shaped space in cubic feet. You can quickly find out the volume in ft3 with this cuft calculator. It can help you determine the volume of a cubic container and the quantity of material necessary to complete the earthworks. You can find the cubic feet of sand or soil. We will discuss how to find cubic feet with various units of volume as well as an example for the measurement of cubic feet in multiple scenarios.

How to use the Cubic ft calculator?

We have made the calculations of cubic feet very easy by delivering a simple interface and freedom to enter measurements in multiple units. To calculate cubic feet using this cubic foot calculator, enter length, width, and height in the given input boxes. After entering the measurements of each side, select the unit of the measurement. It offers multiple units to facilitate your calculations. You can choose from inches, yards, meter, centimeter, millimeter, and feet. Click the "Calculate" button to see the result. It will show you the volume in cubic feet with a diagram so that you can grasp the process of calculation. The cubic inches calculator will also present all steps that are used to evaluate the result, making the calculation more understandable and meaningful.

What is Cubic Foot?

Cubic footage is the volume measured in feet for cubical space. It is the volume of a cube equal to one foot with width, length, and height. Cubic foot measurements are primarily used in the United States, Canada, and Australia. In shipping, freight, and landscaping projects, the cubic footage of an object or space is often necessary.

How to Calculate Cubic Feet?

There is no daily problem, but sometimes you have to quantify something's capacity. Instead of getting a headache while trying to figure out the space capacity of a utensil or a refrigerator, relax.

The volume or capacity in cubic feet can only be measured by taking three measurements, which are width, length, and height. The item you are measuring should be observed carefully. For instance, if the cubic foot of a refrigerator is to be measured, you must measure the space inside the refrigerator rather than the external dimensions. Measure the width, height, and length from inside the refrigerator and note them on a paper or your mobile device.

Once the three measurements are taken, this is just a matter of their multiplication. Or you can use the cubic footage calculator to calculate cubic feet for you if you want.

Cubic Feet Formula

Cubic feet = \( \text{Length (feet)} \times \text{Width (feet)} \times \text{Height (feet)}\)

If the shape is irregular, split it mentally into regular forms and measure the volume separately for each shape and add all of them to get the volume in cubic feet.

Two separate rectangles, one longer and one shorter could be handling an L-shaped case designed to fit a corner or a shorter space. Calculate individually each of them and then combine them for the full capacity of the case.

How to Calculate Cubic Feet to Inches?

Divide the inch number by 12 to convert it to feet if your dimensions are measured in inches. Then take the above steps to measure with feet dimensions.


Let's measure cubic footage of a 40-inch wide, 52-inch high, and 18-inch long bucket.

First of all, convert all the dimensions into feet.

Length = \(\dfrac{18}{12} = 1.5\)

Height = \(\dfrac{52}{12} = 4.33\)

Width = \(\dfrac{40}{12} = 3.33\)

Substitute these values in cubic feet formula.


Cubic feet = \(1.5 \times 4.33 \times 3.33\)


Cubic feet = \(21.62  cu  ft\)

One more way

One other approach is to enter the measurements in inches into the above volume formula and solve the problem to find volume cubic inches first. Then we can convert cubic inches to cubic feet if we divide cubic inches by 1728.

Cubic Feet = \(\dfrac{\text{Cubic inches}} {1728}\)


Put the values in inches in the formula to find the volume in cubic inches.

Volume or Cubic Feet = \(18 in \times 52 in \times 40 in\)

Volume = \(41472\) cubic inches

To find the cubic feet, divide the result by 1728.

Volume = \(\dfrac{73440 cu in}{1728}\)

Volume or Cubic Feet = \(21.67 cu ft\)

How to Find Cubic Feet with some other units?

The process of finding cubic footage is identical to that with measurements in inches if your dimensions are measured in meters, centimeters, yards, or another unit.

Starting with your dimensions being converted to feet. The above calculator also offers entering values in several units, including yards, centimeter, inch, feet, meter, etc.

After converting the measurements into feet from another unit, multiply the values to get volume in cubic feet.

How to Find Cubic Feet of a Cylinder?

Use this formula to find the volume of a cylinder:

Cubic Feet = \(\pi \times \text{radius}^2 \times \text{height}\)

Place the values in the above formula to get the volume of a cylinder. To calculate the volume of a cylinder, you can also use our cylinder volume calculator.

How to measure Cubic Feet with Height and Area?

If the area and height of space are available, then we can find the cubic feet of that space. Isn't it awesome? This is the formula for calculating volume in cubic feet using area and height of a space:

Volume or Cubic Feet = \(\text{area} \times \text{height}\)

The volume of a space can be calculated by multiplying the height and area of that space.

How to Calculate Cubic Feet with Square Feet?

As we know, the volume can be calculated using area and height by multiplying the both, to find cubic footage, simply multiply your square feet by the height in feet.


Calculate the cubic feet of a 4 meter high, 8 square foot area.

Volume = \(8 sq ft \times 4 ft\)

Volume or Cubic Feet = \(32 cu ft\)

Use our square footage calculator if you need to calculate the area in square feet.

Let's convert some cubic units to cubic feet

You can convert to the cubic feet using a simple formula when measuring volume using cubic meters, cubic millimeters, cubic centimeters, cubic inches, or cubic yards.

Unit of volume Method

cubic yards

cubic feet = \(\text{cubic yards} \times 27\)

cubic inches

cubic feet = \(\dfrac{\text{cubic inches}}{1728}\)

cubic meters

cubic feet = \(\text{cubic meter} \times 35.3\)

cubic centimeters

cubic feet = \(\dfrac{\text{cubic cm}}{28316.8}\)



Convert 5 cubic meters to cubic feet.

Find out the formula for the conversion of cubic meter to cubic feet in the above table, which is:

Volume = \(cu ft = cu m \times 35.3\)

Place the value of cubic meter in the formula above.

Volume = \(5 \times 35.3\)

Volume = \(176.5 cu ft\)

So, the conversion from one unit of volume to another is not difficult at all.

What are the measurements of 1 Cubic Foot?

If a cube-shaped space has a volume of one cubic foot, it means it has all sides equal to 1 cubic foot. For further units of measurement, see the following table.

These are the measurements of a cube in various units with the volume capacity of one cubic foot.
