General Chemistry/Units

SI Fundamental Units
These are the seven basic SI units from which all other units are constructed.

SI Derived Units
All other units are derived units. They are built from fundamental units. This is a small selection of units that may be found in General Chemistry.

SI Prefixes
A prefix appears before a unit's symbol when expressing very large or very small quantities. For example: 0.001 kg = 1 g = 1000 mg.

Temperature
One degree Celsius is equal to one Kelvin (in magnitude).

* Notice it is not "degrees Kelvin".
