Is liter the base unit for volume in the metric system?

Answer 1

A derived unit is obtained from a combination of fundamental units. For example, a fundamental unit is a centimeter(cm). A derived unit is a cubic centimeter(cm3), or a cube that is a centimeter on each side. Derived units are used for measuring liquids. A liter is also a derived unit. s-1 is a derived unit too, even though it only consists of one fundamental unit.

There is no such thing as an SI 'fundamental' unit. The term you are looking for is a 'base' unit. Taking this further, the SI base unit for length is the metre, not the centimetre. Derived units are combinations of base units -for example, a metre per second is a derived unit (for velocity), made up of the base units metre and second.

Answer 2

The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.

Answer 3

no its of volume

<><><><><>

Density is mass per volume, typically grams per centimeter cubed (g cm-3).

Additional Answer

There is no SI base unit for volume. The cubic metre (m3) is an SI derived unit. The centimetre is not an SI unit but may be used alongside the SI system.

Answer 4

Although a litre (or liter in US spelling) is a metric unit, it is not an SI unit and most definitely not a Base Unit. It is classified as an unit which 'may be used alongside' the SI system.

In addition to the SI units, there is also a set ofnon-SI units accepted for use with SI, which includes some commonly used non-coherent units such as thelitre.

Answer 5

Answer #1. no liter is not a metrice unit of volume

and the correct answer is SI is a metric unit of volume

Answer #2. The metric system is a term in common usage around the world for a scheme of measurements which is officially known by its French name as Systeme International, or SI. Essentially, metric and SI mean the same thing in American usage. Teachers and textbooks often used to say that the metric unit of volume is the cubic meter and that "liter" or "litre" is not a defined metric unit. This "fact" was based on the set of recommended base units for the metric system adopted in 1954 -- the liter was not among the basic metric units. However, every professional guide to the metric or SI units defines the liter. Officially, the SI defines the liter as a "non-SI unit accepted for use with the SI." Therefore, it seems reasonable to say that the liter is, in fact, a metric unit of volume, while it remains only a lowly stepchild of the official SI.

ANOTHER ANSWER

Yes, a litre is indeed a metric unit for volume. However, it is not an SI unit. In SI, volume is measured in cubic metres. Other examples of metric units that are not SI units include Celsius (temperature), calorie (energy), etc.

Answer 6

Quite simply, because that's the way the SI was defined. It really depends on the choice of base units - for the SI, the meter (a unit of length) was defined as the base unit; meter cubed is the derived unit for volume. A liter is 1/1000 of that, and is therefore also derived from the meter.

You can just as well invent a unit of measures in which a certain volume is the base unit - in this case, the cubic root of this volume would be the (derived) unit of length. But that is not how the SI was defined; presumably, they thought it easier to use a length as the base unit.

Answer 7

Strictly speaking , the unit for volume is cubic metres
