Enter the thickness (in), the outer radius (in), and the inner radius (in) into the Head Gasket Volume Calculator. The calculator will evaluate and display the Head Gasket Volume.

## Head Gasket Volume Formula

The following formula is used to calculate the Head Gasket Volume.

**HGV = pi*T * (Ro – Ri) ^2**

- Where HGV is the Head Gasket Volume (in^3)
- T is the thickness (in)
- Ro is the outer radius (in)
- Ri is the inner radius (in)

## How to Calculate Head Gasket Volume?

The following example problems outline how to calculate Head Gasket Volume.

**Example Problem #1**

- First, determine the thickness (in).
- The thickness (in) is given as .25.

- Next, determine the outer radius (in).
- The outer radius (in) is calculated as: 4.

- Next, determine the inner radius (in).
- The inner radius (in) is found to be: 3.

- Finally, calculate the Head Gasket Volume using the formula above:

HGV = pi*T * (Ro – Ri) ^2

Inserting the values from above yields:

HGV = pi*.25*(4 – 3) ^2 = .785 (in^3)

**Example Problem #2**

The variables needed for this problem are provided below:

thickness (in) = .6

outer radius (in) = 7

inner radius (in) = 3
