Slide 1: 

The Metric System

Metric System : 

Metric System The metric system is based on a base unit that corresponds to a certain kind of measurement: Length = meter (m) Volume = liter (l) Weight (Mass) = gram (g)

Metric System : 

Metric System The prefixes we will use are: k = kilo h = hecto dk = deka d = deci c = centi m = milli

Metric System : 

Metric System Prefixes plus base units make up the metric system. Example: Centi + meter = Centimeter (cm) Kilo + liter = Kiloliter (kl) Deka + gram = Dekagram (dkg) Milli + meter = Millimeter (mm)

Metric System : 

Metric System *Remember… Abbreviation Name m meter mm millimeter d deci dl deciliter dg decigram l liter dk deka dkl dekaliter

Metric System : 

Metric System An easy way to move within the metric system is by moving the decimal point one place for each “step” desired If you move to the left in the diagram, move the decimal to the left If you move to the right in the diagram, move the decimal to the right

Metric System : 

Metric System Example 1: meters to kilometers So for every “step” from the base unit to kilo, we moved the decimal 1 place to the left.. How many places do we move the decimal to the left?(

Metric System : 

Metric System Example 1: grams to centigrams So for every “step” from the base unit to centi, we moved the decimal 1 place to the right.. How many places do we move the decimal to the right?

Metric System : 

Metric System Summary Base units in the metric system are meter, liter, gram For conversions within the metric system, each “step” is 1 decimal place to the right or left Using the diagram below, converting to the right, moves the decimal to the right Using the diagram below, converting to the left, moves the decimal to the left

Metric System EXAMPLES: 1. 3.21 m = ___________ mm 2. 0.4 g = ___________ kg 3. 4. 5. 6.
