This calculator will find the volume of a cone using diameter and height. It will return the volume of the cone in cubic inches, centimeters, ounces and gallons.

## How To Calculate The Volume Of A Cone

### Example formula for an *8* inch tall cone with a *14* inch diameter base.

Divide the diameter in half (**14** / 2 = 7) to find the radius.

Then enter your height and base radius into the following formula:

π * (radius * radius) * height / 3

Just for reference, pi (π) equals 3.141592653.

After you’ve entered the dimensions of the cone in our example, the formula should look like this:

3.141592653 *(

7*7) *8/ 3

Using this formula, our 14 x 8 inch cone equals **410.5** cubic inches

## How To Convert Cubic Inches To Centimeters, Feet, Ounces And Gallons

If we needed to know how many cubic feet, we would divide cubic inches by 1728.

To convert cubic inches to ounces, you would multiply cubic inches by 0.554113.

To convert cubic inches to gallons, you would multiply cubic inches by 0.004329.

To convert cubic inches to centimeters, you would multiply cubic inches by 16.3871
