1. Metric System and Unit Conversion
The greatest Chemistry Teacher this world has ever known

2. International System of Measurement
Internationally used system of measurement known as the “Metric System”

3. Benefits of Using the Metric System
Scientist all over the world use this system.
They can share and understand each other’s work.
Based on multiples of ten. Makes for easier conversions.

4. SI Base units

5. Volume
The amount of space an object takes up.
Base unit is cm3

6. Mass The amount of matter in an object.
Base unit is the kg because the gram is too small.

7. Weight
The pull gravity has on the mass of an object.

8. Fluid Volume
When dealing with a fluid (gas or liquid) the most commonly used unit is the liter (L)
1ml = 1cm3

9. SI Prefixes

10. Dimensional Analysis
Method of converting from one unit to another of equal value using conversion factors.

11. Conversion Factors
These are fractions that are equal to one because the top is equal to the bottom despite the differing units.
Multiplying anything by one will not change the number.
Conversion factors spawn from two numbers that are equal to each other.
Ex. 100cm = 1m
100𝑐𝑚 1𝑚 or 1𝑚 100𝑐𝑚

12. Using Dimensional Analysis
How many mg are in 1.32kg?
= 𝑚𝑔
How many seconds are in your lifetime?
How many cases of pop will you drink in your lifetime?
1.32kg
1000g
1000mg
1kg 1g

13. Converting Complex Units
What is 19 in2 in ft2?
