Cubic Feet Calculator
Cubic foot (cft) calculator is an online tool for computing the volume of a material or space. This tool is one of the best because it has the following features:
- Users can enter values in different units of measurement like inches, meters, etc.
- Full calculation process that first finds the volume in the inputted unit and then converts it into cubic feet.
- It gives a labeled diagram of the cube that has a geometry according to the entered values.
What is a cubic foot?
It is a unit of volume. A cubic foot is not related to cubes only but it actually means what is the volume of the body in terms of a cube that is 1 foot tall, long, and wide.
For example, if you want to find out the volume of cement in cubic feet, it will be the volume of cement that can fit into the cubic cylinder of volume 1ft3 (as shown in the image).
Cubic feet formula
The formula to find the volume in cubic feet is the same as the volume. Just make sure your values are in feet.
Volume in cft = Length (ft) x Width (ft) x height (ft)
Note that to use this formula, the body must have noticeable length, width, and height, unlike spheres and cones.
For such bodies, you convert the measurements in feet and then find the volume using their specified volume formulas.
How to calculate cubic feet?
To find the volume in the cubic feet yourself, you will need to follow the instructions below.
- Measure the height, length, and width of the object. For materials like cement or mud, measure the cylinder that is holding them.
- Convert the values in feet.
- Multiply the three values.
And just like that, you have the volume in cft. Maybe confirm your answer from the cubic ft calculator afterward.
Example:
Find the volume of a rectangle in cubic feet of a cylinder with the following dimensions.
Length = 20 meters
Height = 15 meters
Width = 20 meters
Solution:
By using the usual volume formula, you will get the result in cubic meters. So to calculate in cubic feet.
Step 1: Convert the meters to feet.
As 1 meter = 3.28084 feet
Length = 20 m = 20 x 3.28084 feet
= 65.17 feet
Height = 15 m = 15 x 3.28084 feet
= 49.213 feet
Width = 20 m = 20 x 3.28084 feet
= 65.17 feet
Step 2: Multiply the values according to the cubic feet formula.
= L x H x W
= 65.17 x 49.213 x 65.17
= 211888 ft
Calculating cubic feet from other units
To find the volume in cubic feet when the measured lengths are in other units, you can use the following formulas.
From inches:
Divide each length by 12.
From yards:
Multiply each length by 3.
From meters:
Multiply by 3.28084
From millimeters:
Multiply by 0.00328
From centimeters:
Multiply each value by 0.0328084
