A dimensionless quantity is a pure number without any physical units, often arising from the ratio of two quantities with the same dimensions, allowing for comparison across different systems. These quantities are crucial in scientific fields as they provide scale-invariant insights, facilitating the understanding of physical phenomena and the derivation of universal laws.
