The Weight and Volume Calculator contains volume and mass / weight equations for a variety of geometric shapes and provides the mean density for a large number of substances.

# Description

The Weight and Volume Calculator Volume and Weight/Mass equations in this calculator let the user:

1. Choose a geometric shape or container type,
2. enter the dimensions of the object to determine the Volume, and
3. enter a mean density to calculate the object's approximate mass.  Assuming nominal Earth gravity, the mass can be converted to nominal Earth surface weight (e.g. pounds from kilograms).

vCalc provides a lookup function that contains the mean density in kilograms per cubic meter of hundreds of substances from farm commodities (e.g. grains, woods, etc) to quary items (types of stone and sand) to commonly transported liquids (e.g. water, diesel).

The basic formula for all of the equations is this: various frustums

 "mass" = mu"Density" * "volume"

## Geometric Shapes or Containers

The mass equations in this calculator are based on three dimensional (3D) shapes and equations to calculate their volume.  The geometric shapes included in this calculator are:

• Cube, Box, Cone, Cone (frustum), Cylinder, Slanted Cylinder,
• Ellipsoid, Capsule, Bottle, Paraboloid, Pyramid, Pyramid Frustum,
• Sphere, Sphere Cap, Sphere Segment, Prism, Torus, Chamfer

## Mean Density

At the bottom of the Weight tab, spheresvCalc provides a look-up function for many mean densities which can be used with the container shape to determine the weight of the contents of the container (e.g. water, grain, oil).  Using the meadDensity Lookup, the user can choose any of hundreds of substances and vCalc will return the mean density:

• Basic Elements
• Farm commodities
• Metals and Alloys
• Minerals, Rocks, Sands and Soils
• Oils and various industrial liquids
• Types of Wood
