   What is the difference between numbers and units in chemistry?

   • Numbers tell “how much,” and units tell “of what.” Chemistry uses a set of fundamental units and derived units from SI units. Chemistry uses a set of prefixes that represent multiples or fractions of units. Units can be multiplied and divided to generate new units for quantities.

   How many base units are there in chemistry?

   • The United States is one of the few countries that has not. Base (or basic) units, are the fundamental units of SI. There are seven base units, which are listed in Table 1.6.1 1.6. 1, Chemistry uses five of the base units: the mole for amount, the kilogram for mass, the meter for length, the second for time, and the kelvin for temperature.

   What are derived units?

   • It is important to understand, however, that all of these can be expressed in terms of the SI base units; they are consequently known as derived units. In fact, most physical quantities can be expressed in terms of one or more of the following five fundamental units: Consider, for example, the unit of volume, which we denote as V.

   What are honorary units in chemistry?

   • There is a category of units that are “honorary” members of the SI in the sense that it is acceptable to use them along with the base units defined above. These include such mundane units as the hour, minute, and degree (of angle), etc., but the three shown here are of particular interest to chemistry, and you will need to know them.

   We will use most of the fundamental units in chemistry. Initially, we will deal with three fundamental units. The metre (m) is the SI unit of length. It is a little longer than a yard (see Figure 2.4 “The Metre”). The SI unit of mass is the kilogram (kg), which is about 2.2 pounds (lb). The SI unit of time is the second (s). Figure 2.4 “The Metre.”

    All measuring units can be defined in terms of a very small number of fundamental ones that, through "dimensional analysis," provide insight into their derivation and meaning, and must be understood when converting between different unit systems. 1. Units of Measure.
