Differentiate the two system of measurement?

Answer 1

A measurement must be quantitative, as the result is a quantity. A qualitative property is something that can't be measured, such as your opinion of someone, or of a book you have read.

Absolutely incorrect. In science you have both qualitative and quantitative measurements. A quantitative measurement is just as it sounds, measuring the quantity of something. A qualitative measurement systematically measures the quality of a system.

Temperature is a qualitative measurement of heat. Where as heat is a quantitative measurement of energy. You can't "add" temperature but you can "add" heat to a system by increasing the temperature or the mass of the system.

Mass is a quantitative measurement, where as weight is a qualitative measurement of the force of gravity on a mass and is dependent on where it is measured (gravity).

If you can "add" or "subtract" something it is quantitative. If you can only "change" it it is qualitative. Thus it is scientifically incorrect to say "adding weight", you must say "increasing weight".

Answer 2

A quantitative measurement measures the amount (quantity) of the parameter or substance being measured (presumably with a given degree of accuracy) - so they give a numerical output of some kind. A non-quantitative test (i.e. qualitative) doesn't measure the quantity - it may register the presence of an item (e.g. a "go/no-go" test) without a statement of quantity or accuracy or it may be an identity test (things like non-quantitative IR or GC fingerprinting or Mass Spec structural determinations all fall into this category)

Metric system and English system :)
