In metrics, the units of measurement used to express the volume of smaller objects would be the liter, deciliter, centiliter and milliliter. The English system of measurement uses gallons, quarts, pints, and cups to express the volume of smaller objects.
Cubic units are used to measure volume. These units are m3 ,cm3 etc.
Liters and milliliters are the units used most often to express the volume of liquids.
Mass is expressed in grams in the SI system and slugs in the English system. (these are the base units obviously multiples of these units exist. ex: kg). Volume is expressed as a cubic of any unit of length ex: M^3.
You can use any measurement but only if your adding cubic to it
litres cubic metres
cubic measures such as cubic feet, cubic meters
Density = mass / volumeIn SI units: mass is expressed in kilograms volume is expressed in cubic meters Therefore, density is expressed in kilograms /cubic meters. (In practice, the unit kilogram/liter, which is equivalent to gram / cubic centimeter, is often still used.)
The volumes of all objects are expressed in the third power of whatever units are being used to measure their dimensions. For example, if an object is very small and you measure its dimensions in millimeters, its volume would be expressed in cubic millimeters.
cubic units
If you mean the units, capacity, or volume, is expressed in cubic meters, cubic decimeters (= liters), cubic centimeters (= milliliters), etc.
Litre is a unit used to express volume
Any unit of mass divided by any unit of volume is a perfectly good unit of density, for any kind of substance.
