Question

can a physical quantity have two or more units? give example ​

Answer 1

Answer:

physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed by either a numerical value, the product of a numerical value and a unit or a finite sequence of numerical values and units. For example, the physical quantity specific gravity may be represented by just the number "2.3", the physical quantity mass can be quantified as "7.42 kg", where "7.42" is the numerical value and "kg" is the unit. The vector physical quantity, velocity, may be represented as <2.3 m/s, 3.5 m/s ,1.7 m/s>, where the three values are the components of the velocity in a particular coordinate system.
