Transcript Measuring Capacity, Weight, and Temperature

Measuring Capacity, Weight,
and Temperature
Section 7.2
Objectives
• Convert and perform operations on units
of capacity
• Convert and perform operations on units
of weight
• Convert units of temperature and time
Objective 1:
Convert and perform operations
on units of capacity
Objective 1
•
•
•
•
•
Units of capacity measure liquid quantities
English units
Metric units
Conversion – use same technique
To convert units of capacity
– Multiply by unit fraction with desired units in
numerator and original units in denominator
– Simplify
Objective 1
• Performing operations on units of capacity is
done the same as for units of length
• To multiply or divide a measurement by a
number
– Multiply or divide numbers and write unit of measure
• To add or subtract measurements
– If units of measure are unlike, convert to like
measures
– Add or subtract numbers and write unit of measure
Objective 2:
Convert and perform operations
on units of weight
Objective 2
•
•

Units of weight measure heaviness
English units
Metric units

Objective 3:
Convert units of temperature and
time
Objective 3
•
•
•
•
Units is degrees
English system – Fahrenheit
Metric system – Celsius
Conversion is different
– Fahrenheit vs. Celsius – temperatures of
freezing and boiling water
– Unlike other measurements, temperature has
different starting points
Objective 3
• To convert from F to C
5
C   (F  32)
9
or
5
C  (F  32) 
9
• To convert from C to F
9
F   C  32
5
or
5
F  C   32

Objective 3
• Converting units of time – use same
technique
– Multiply by unit fraction with desired units in
numerator and original units in denominator
– Simplify
