The Weight or Mass of an Ellipsoid calculator computes the weight or mass of an ellipsoid with semi-axes of lengths  a, b, and c (see diagram), where the composition of the ellipsoid has a mean density (mD).

INSTRUCTIONS:  Choose your preferred length units (e.g. meters, miles) and enter the following:

•  (a)  semi-axis of the ellipsoid.
•  (b)  semi-axis of the ellipsoid.
•  (c)  semi-axis of the ellipsoid.
•  (mD) the mean density of the sphere

Mass of Ellipsoid (m): The mass of the ellipsoid is returned in kilograms. However, this can be automatically converted to other mass and weight units (e.g. pounds, tons, grams) via the pull-down menu.

Note: the mean density (mD, μD, ρ) of many common substances, elements, liquids and materials can be found by CLICKING HERE.

## 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 = ρ * volume

where:

• rho is the mean density
