2 .2 SI Units

1. A “base unit” is the foundational unit of measurement like “m”, it’s more familiar unit.

2. Here is some example of base unit in the international system. (SI)

                            Quantity                     Written Unit                      Symbol

                            Length                      meter                                m

                            Mass                          gram                                   g

                            Time                           second                                s

3. There are also some prefix using before the unit: mega, kilo, deci, centr, milli, micro, as symbol: M, k, d, c, m.

4. There are some equivalences like 1ml= 1cm3 1m3=103L 1t=103kg

5. Lots of re-write question are in this topic. Transferring one unit to another, we should be careful of the prefix and the exponential.
