2. What is the Metric System
A system in which objects can be measured using standardized units

3. Ways size can be measured
Distance (meter)
Length
Height
Depth
Weight (Grams)
Area (liters, cm3)
Volume
Surface area

4. Measurements Measurements
Are used to describe matter and its changes during reactions
Valid measurements must have 2 criteria
Quantity (how much)
Unit (type of object)

5. Basic Units The metric system is based on a scale of 10
The basic units for measuring using the metric system are:
Meters (distance)
Liters (volume)
Gram (mass/weight)

6. Prefix Values K Kilo H Hecto D Deca Base Value d. deci c. centi. m.
milli

7. Prefix Values Kilo X 1000 Hecto X 100 Deca X 10 Base Value 1 Deci ÷ 10
Takes 10 of these to equal 1 base unit
÷ 10
Centi
Takes 100 of these to equal 1 base unit
÷ 100
Milli
Takes 1000 of these to equal 1 base unit
÷ 1000
