The Square Torus Mass or Weight calculator computes the volume of a square torus based on the thickness (height) and the surface area.   The surface area is calculated as the difference between two circles with diameters of d1 and d2.

INSTRUCTIONS: Choose units and enter the following:

• (T) Torus Thickness or Height 
• (d1) Inner diameter
• (d2) Outer diameter
• (mD) Mean Density

Torus Mass or Weight (M): The calculator computes the mass of the square torus in grams.  However this can be automatically converted to compatible units via the pull-down menu.

The Math

The equation for the square torus volume is:

        `M = pi * T *[ (d_2/2)^2 - (d_1/2)^2] * mD`

where:

• M is the Mass or Weight of the Square Torus
• T is the thickness or height of torus
• d₂ is the outer diameter
• d₁ is the inner diameter
• mD is the density of material
