The Weight of a Cone calculator computes the mass (weight) of a right circular cone or cone frustum defined by a top radius (a) and base radius (b), height (h) in between, using the mean density (mD) and volume to calculate the mass of the object. The frustum of a cone is also known as a truncated cone.
INSTRUCTIONS: Choose units and enter the following:
Weight of a Cone (M): The calculator computes the mass/weight of the cone in grams or kilogram. However, this can be automatically converted to numerous other mass/weight units (e.g. pound, tons) via the pulldown menu. Note: For a complete cone, simple let the top radius (a) remain as zero.

The formula for the mass or weight of the frustum of a cone is:
`M = [1/3 * π * h(a^{2}+ a*b+ b^{2})]*ρ`
where:
This calculator first computes the Volume of the Frustum of a Cone (CLICK HERE), and then uses that volume with the mean density as follows:
The mean density (mD, μD or ρ) of many common substances, elements, liquids and materials can be found by clicking HERE (e.g. the μD_{(water)} is 1000.0 kg/m³).
Metals are materials characterized by its physical and chemical properties, primarily its ability to conduct electricity and heat, its luster or shine when polished, its malleability (ability to be hammered or pressed into shapes), and its ductility (ability to be drawn into wires). Metals typically have a crystalline structure and are found naturally in solid form (with the exception of mercury, which is a liquid at room temperature).
Metals Densities

Metals make up a large portion of the periodic table of elements, with examples including iron, copper, gold, silver, aluminum, and titanium, among many others. Metals are essential in various industries such as construction, manufacturing, electronics, transportation, and energy production due to their unique properties and versatility.
Metals are generally dense materials. Density is a measure of how much mass is contained in a given volume. Metals tend to have high densities because their atoms are closely packed together in a crystalline structure. This close packing of atoms contributes to their characteristic properties such as strength, malleability, and conductivity.
However, it's important to note that the density of metals can vary widely depending on factors such as their elemental composition, crystal structure, and any impurities present. For example, some metals like lead and platinum are denser than others like aluminum or magnesium.
The Weight of Metal Calculator contains functions and data to compute the weight (mass) of metal objects based on their size, shape and the density of the metal. The Weight of Metal functions are:
