The Torus Weight (Mass) calculator computes the weight or mass of a torus (circular tube) with an inner radius of (a), an outer radius of (b) and a mean density (mD). 
Torus - Circular Tube
INSTRUCTIONS: Choose units and enter the following:
- (r) The inner radius
- (R) This outer radius
- (mD) The mean density of the material in the torus.
Torus Mass / Weight (M):. The calculator returns the mass in kilograms. However, this can be automatically converted to compatible units via the pull-down menu.

Description
This formula computes the volume of the geometric shape based on the input parameters. With the computed volume, this formula then executes the simple equation below to compute the approximate mass of the object.
`mass = mu_(density) * volume`
The mean density (`mu_(density)`) of many common substances, elements, liquids and materials can be found by clicking HERE (e.g. the `mu_(density) (water)` is 1000.0 kg/m³).
