Enter a value for all fields

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 the torus - (
**b**) - Outer radius of the 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
