This tool calculates the basic geometric properties of a ring torus. Enter the shape dimensions Rout and Rin below. The calculated results will have the same units as your input. Please use consistent units for any input.
The torus is a 3-dimensional object, that can be created through rotation a circular disc around a circle. The volume of a torus is given by the formula:
where the outer radius of the torus and its inner radius.
The surface area of the torus is given by the next formula:
