Organizing and summarizing search results for youThe International System of Units (SI) is constructed from seven base units. These units are adequate to describe most of the measurements used in science, industry and commerce. The seven base units are:- Length: meter (m)
- Mass: kilogram (kg)
- Time: second (s)
- Electric current: ampere (A)
- Thermodynamic temperature: kelvin (K)
- Amount of substance: mole (mol)
- Luminous intensity: candela (cd)
There are also SI prefixes that can be used to express very large or very small quantities.
