- A physical quantity is a property of a material or system that can be quantified by measurement12. It can be expressed as a value, which is the algebraic multiplication of a numerical value and a unit of measurement1. In physics, physical quantities are any physical properties that can be quantified and measured using numbers2. Examples of physical quantities include mass, amount of substance, length, time, temperature, electric current, light intensity, force, velocity, and density, among others2.Learn more:✕This summary was generated using AI based on multiple online sources.
