What is the correct unit to measure volume?

Answer 1

Since it is so wide, and so long and so high it is a cubic unit of length, e.g. cubic meter. A special cubic measure is 1 cubic decimeter, which is 1 liter, that when filled with water weighs 1kg.

Answer 2

Système International d'Unités, or shortly Système International (SI System) is the complete metric system of units of measurement universally accepted by all scientists.

In SI System, the fundamental quantities and their units (given in brackets) are as below.

Length (meter)

Mass (kilogram)

Time (second)

Electric current (ampere)

Temperature (kelvin)

Amount of matter (mole)

Luminous intensity (candela)

Hence, the correct unit to measure volume of any matter (solid, liquid or gas) is cubic meter ie, which is the product of meter x meter x meter. Cubic meter(m3) is a compound unit derived from SI units.

The non-standard SI units like cubic millimeter, cubic centimeter (cc), cubic hectometer etc are also used for volume of solids. The litre and its subdivisions and multiples like millilitre, hectolitre etc. are used for volumes of liquids and gases. Although the litre is not an SI unit, it is accepted for use with the SI.

The spelling of meter and litre may differ according to language or dialect.

In the Imperial system, the cubic inch, cubic foot, cubic yard etc. are used for solids and the gill, pint, gallon etc. for liquids.

Increasingly, the metric system is displacing the Imperial system in Britain and former British colonies except in common use for familiar concepts, e.g. "a pint of beer", and for distances, where miles are still used rather than kilometres (however, some ex-colonies, e.g. Australia, have converted to kilometres).

In the USA, a variant on the Imperial system is generally used but the liquid measures, although bearing the same names as the Imperial ones, are smaller in some cases. The metric system is increasingly used in industry, especially when manufacturing goods for export.
