The **Volume of a Torus** calculator computes* Torus * the volume of a torus (circular tube) with an inner radius of (a) and an outer radius of (b).

**INSTRUCTIONS:** Choose units and enter the following:

- (
**a**) Inner Radius of Torus - (
**b**) Outer Radius of Torus

**Volume of a Torus (V):** The calculator returns the volume (V) in cubic meters. However, this can be automatically converted to compatible units via the pull-down menu.

The formula for the volume of a torus is:

where:

- V is the volume of the torus
- a is the inner diameter
- b is the outer diameter

- Volume of a Torus based on the inner and outer radii
- Volume of a Torus based on the outer radius (R) and the radius of the tube (r)
- Mass or Weight of Torus
- Surface Area of a Torus

**Volume **is a three dimensional measurement of the amount of space taken up by an object. Volume units are cubic measurements for solid objects such as cubic inches and cubic meters. Fluid objects have separate units such as fluid ounces, gallons, barrel and liters.

The volume of an object can measured by the liquid it displaces or be calculated by measuring its dimensions and applying those dimensions to a formula describing its shape. Many such calculations are available in the following list of calculators.

In many cases, the calculators are for a column with a geometric shaped base and vertical sides. The most basic form is an Area times a Height.
