- The metric system that we use is the same worldwide and therefore it is called the International system of units (or SI units), where all units are expressed in terms of seven base units. These are seven base units: Meter (m) for Length Kilogram (kg) for Mass

- Density and Percent Composition
For example, we usually measure the volume of a liquid sample with pipettes, burets, graduated cylinders, and volumetric flasks (Figure \(\PageIndex{1}\)), whereas we usually measure the mass of a solid or liquid substance with a balance (Figure \(\PageIndex{2}\)).
Learning Objectives. Explain the process of measurement and describe the three basic parts of a quantity. Describe the properties and units of length, mass, volume, density, temperature, and time. Recognize the common unit prefixes and use them to describe the magnitude of a measurement.
We use the mass and volume of a substance to determine its density. Thus, the units of density are defined by the base units of mass and length. The density of a substance is the ratio of the mass of a sample of the substance to its volume. The SI unit for density is the kilogram per cubic meter (kg/m 3).

length: The measurement of the extent of something along its greatest dimension; meter: The SI basic unit of length, or linear measure; volume: The amount of space occupied by a sample of matter. The volume of a regular object can be calculated by multiplying its length by its width by its height.
