1. METRIC SI

1.1. Definition

1.1.1. The metric system is an internationally recognised decimalised system of measurement. It is now known as the International System of Units (SI). (Wikipedia)

1.2. Types

1.2.1. Base Units

1.2.1.1. meter for length

1.2.1.2. kilogram for mass

1.2.1.3. second for time

1.2.1.4. ampere for electric current

1.2.1.5. kelvin for temperatue

1.2.1.6. candela for luminous intensity

1.2.1.7. mole for quantity

1.2.2. Derived Units

1.2.2.1. Electromagnetism Quantities: volt, ohm, tesla, weber, farad, henry, siemens and coulomb

1.2.2.2. Mechanical Quantities: watt, newton, joule, pascal.

1.2.2.3. Electromagnetic Radiation: becquerel, sievert, lux, lumen

2.1.4.1.1. Depend on the quantity of matter contained in a system

2.1.4.1.2. Examples: mass, volume, heat capacity, internal energy, enthalphy, entropy

2.1.4.2. Intensive

2.1.4.2.1. Depend only upon the amount of the substance present in the system
