Question

In both metric and imperial systems, which of the following is/are the types of measurement units?

I. Basic units

II. Derived units

1. Neither I nor II
2. Both I and II
3. Only I
4. Only II

Answer 1

Correct Answer - Option 2 : Both I and II

A standard unit of measurement refers to the unit adopted conventionally to measure a particular quantity. There are two major systems of the standard measuring unit are:

• The Metric System: This internationally recognized system of measurement uses meter, litre, and gram to measure length, capacity, and weight respectively.
• The British or Imperial System: This traditional system of measurement uses foot, pound, second to measure length, mass and time respectively.
• Basic units are those units which are used for basic quantity (i. e. which are not derived from other quantity.). For example: metre (length), kilogram (mass).
• Derived units are those units which are formed by the combination of basic units. For example, Newton is the combination of unit of mass and acceleration (kilogram metre per second square)

Hence, both types of units can be used for measurement.
