SI Units and Dimensional Analysis
SI Units
Why do we use SI Units?

The beauty of the metric system is that it is based on the number 10.

5 important base units all Chemistry students need to understand, but first... Group activity
What units would we use?
Length or distance
weight
Volume
Time
Temperature
Five Base Units
Length (l): Meter (abbr. M)
Mass (m): Kilogram (abbr. Kg)
Time (t): Second (abbr. S)
Thermodynamic temperature (T): Kelvin (abbr. K)
Amount of Substance (n): Mole (abbr. mol)
Dimensional Analysis
Use dimensional analysis (or converting) when you have one measurement and you need a smaller or larger one.

2 different ways: Ladder method or conversion factor
Ladder Method
1st: Determine your starting point.

2nd: Count the "jumps" to your ending point.

3rd: Move decimal the same number of jumps in same direction.
Conversion Factor
A ratio that is derived from the equality of two different units and that can be used to convert from one unit to the other.

Mass Given C.F. Mass Wanted
3200g 1Kg/1000g 32Kg
