Example 8-6b Objective Change metric units of length, capacity, and mass

Example 8-6b Vocabulary Meter The base unit of length in the metric system

Example 8-6b Vocabulary Metric System A base-ten system of measurement using the base units: Meterlength Kilogram mass Litercapacity

Example 8-6b Vocabulary Gram Measures mass (the amount of matter in an object)

Example 8-6b Vocabulary Kilogram The base unit of mass

Example 8-6b Vocabulary Liter The metric measure for capacity (the amount of dry or liquid material an object can hold)

Lesson 8 Contents Example 1Convert Units of Length Example 2Convert Units of Length Example 3Convert Units of Mass Example 4Convert Units of Mass Example 5Convert Units of Capacity Example 6Convert Units of Capacity

Example 8-1a Complete 28 cm mm. 1/6 Write conversion formula What you know 1  Conversion Ratio Replace what you know 28 cm Bring down the 1  1  Begin with unit of measure you are converting to mm Put the unit of measure of what you know in the denominator cm

Example 8-1a Complete 28 cm mm. 1/6 Find your base unit of measure 28 cm 1  mm cm mm = millimeter cm = centimeter Meter is your base measure Determine how many millimeters are in a meter The prefix “milli” means 1,000 So place 1,000 next to mm 1,000

Example 8-1a Complete 28 cm mm. 1/6 28 cm 1  mm cm 1,000 Determine how many centimeters are in a meter The prefix “centi” means 100 So place 100 next to cm 100 Cancel out units that are the same in the numerator as in the denominator

Example 8-1a Complete 28 cm mm. 1/6 28 1  mm1,000 Follow order of operations 100 PEMDAS Remember: Fraction bar is a grouping symbol Multiply the numerators 28  1,000 28,000 Bring down the mm 28,000 mm Multiply the denominators 100

Example 8-1a Complete 28 cm mm. 1/6 Remember: Fraction bar means division Divide 28,000 by 100 Bring down the mm 28,000 mm 100 280 280 mm Answer: 280 mm

Example 8-1b Complete 3,400 mm cm. Answer: 340 cm 1/6

Example 8-2a Complete 438 cm m. 2/6 Write conversion formula What you know 1  Conversion Ratio Replace what you know 438 cm Bring down the 1  1 Begin with unit of measure you are converting to  m Put the unit of measure of what you know in the denominator cm

Example 8-2a Complete 438 cm m. 2/6 438 cm 1  m cm Find your base unit of measure m = meter cm = centimeter Meter is your base measure Determine how many meters are in a meter Since meter is the base then there is 1 meter in a meter So place 1 next to m 1 1

Example 8-2a Complete 438 cm m. 2/6 438 cm 1  m cm 1 Determine how many centimeters are in a meter The prefix “centi” means 100 So place 100 next to cm 100 Cancel out units that are the same in the numerator as in the denominator

Example 8-2a Complete 438 cm m. 2/6 438 1  m 1 100 Follow order of operations PEMDAS Remember: Fraction bar is a grouping symbol Multiply the numerators 438  1 438 438 m Bring down the m Multiply the denominators 100

Example 8-2a Complete 438 cm m. 2/6 438 m 100 Remember: Fraction bar means division Divide 438 by 100 Bring down the m 4.38 m Answer: 4.38 m

Example 8-2b Complete 7.5 m cm. Answer: 750 cm 2/6

Example 8-3a Complete 72 g mg. 3/6 Write conversion formula What you know 1  Conversion Ratio Replace what you know 72 g Bring down the 1  1  Begin with unit of measure you are converting to mg Put the unit of measure of what you know in the denominator g

Example 8-3a Complete 72 g mg. 3/6 72 g 1  mg g Find your base unit of measure mg = milligram g = gram Gram is your base measure Determine how many milligrams are in a gram The prefix “milli” means 1,000 So place 1,000 next to mg 1,000

Example 8-3a Complete 72 g mg. 3/6 72 g 1  mg g 1,000 Determine how many grams are in a gram Since meter is the base then there is 1 gram in a gram So place 1 next to g 1 Cancel out units that are the same in the numerator as in the denominator

Example 8-3a Complete 72 g mg. 3/6 72 1  mg 1,000 1 Follow order of operations PEMDAS Remember: Fraction bar is a grouping symbol Multiply the numerators 72  1,000 72,000 72,000 mg Bring down the mg Multiply the denominators 1

Example 8-3a Complete 72 g mg. 3/6 72,000 mg 1 Remember: Fraction bar means division Divide 72,000 by 1 72,000 72,000 mg Bring down the mg Answer: 72,000 mg
