Question

Can a quantity have different dimensions in different system of units

Answer 1

Answer:

Yes, A quantity can have different dimensions in different system as CGS,MKS etc

So, quantity can have different dimensions in different system of units

Answer 2

No, a quantity can never have different dimensions in different system of units. But their units can be different in different system of units like Newton as the unit of force in meter, kilogram, and second (MKS) system and as ergs in Centimetre–gram–second (CGS) system.

What is the difference between dimensions and units?

• The distinction between unit and dimension as nouns is that a unit is (in science) a standard measure of a quantity, but a dimension is just one feature of a thing.
• For each unit, unit is used as an adjective.
• To dimension anything is to mark, cut, or shape it according to predetermined measurements.
• A unit incorporates a trait of scale, whereas a dimension does not. This is another distinction.

Therefore, a quantity can never have different dimensions in different system of units. However, since they each represent a separate physical quantity, it is possible to have the same dimension but different units.
