Sphericity refers to the state of being a perfect sphere. Spheroidicity refers to the state of being a spheroid – an object that is almost, but not exactly, spherical (like a slightly squashed sphere).
No, it is a very rare, technical term used almost exclusively in scientific and mathematical fields.
Yes, it is often a quantifiable property. It can be expressed as a ratio of dimensions (e.g., polar vs. equatorial diameter) or through more complex mathematical formulae comparing the object's shape to a reference sphere.
The planet Earth is an oblate spheroid. Its spheroidicity is relatively high (it is very close to a sphere) but measurable, as it is slightly flattened at the poles and bulging at the equator due to rotation.
