First Lesson: Unit Conversion!

All measurement in science come in two parts: the number and the unit, having one without the other makes no sense!


SI Metric:

1. SI stands for systeme internationale

2. It is a French system dating back to the early 1800s

3. It uses powers of 10!

The Canceling Method for unit conversions: ^_^
Derived quantities include units created by combining base quantities through multiplication or division
ex. m^2(m*m)——Area
     cm^3 (cm*cm*cm)——Volume
     km/h  or  m/s——speed
     g/L  ——density


Convert:
ex: 8km/ms——>cm/s
8km       10^3 m    10^2 m     10^3 ms
—— × ———— × ———— ×———— = 8×10^8 cm/s
 ms          1km            1m              1s
