Derived Units
Area – amount of surface included within a set
of boundaries; expressed in square units of
length, e.g., m2
Volume – amount of space occupied by an
object, e.g., m3 for solids or mL or L for liquids
Density – amount of matter that occupies a
given space; mass/volume, e.g., g/mL
Basic units: m, l, g

The Metric Temperature Scale
Also called the centigrade scale.
Definitions
0°Celsius(C) = 32°Fahrenheit(F) = water freezes
100°Celsius = 212°Fahrenheit = water boils
Conversions
°Celsius = 5/9 X (°Fahrenheit - 32°)
°Fahrenheit = (9/5 X °Celsius) + 32°
30 is hot,
20 is nice,
10 is chilly,
0 is ice.
