Hi class,
today we discussed the use of the metric system in class.
In science the metric system of meters, liters and grams is used instead of the English (or Standard) system of feet, gallons, and pounds because of the ease. Metric is a base 10 system allowing easy conversions between units.
Here is the link to a powerpoint presentation that can help


Notes:
Base units of length: Meter
Base units of mass: Grams
Base units of volume: Liters

Prefixes:
Milli: Divide by 1000
Centi: Divide by 100
Deci: Divide by 10
Deka: Multiply by 10
Hecto: Multiply by 100
Kilo: Multiply by 1000

1 meter (m) = 10 decimeters (dm)= 100 centimeters (cm)= 1000 millimeters (mm)
1000 meters = 1 kilometer (km)
1 meter = 100 hectometers (hm)
1 meter = 10 dekameter (dam)

You can do the same for units of mass, and volume, by replacing the base units.
