Measurement
The
five forms of measurement listed below are those that are most
commonly used.
-
Length: A
measure of an object from one end to the other. This measure
is similar to distance, which measures the
space between points or objects. When you measure the distance
around an object, you are finding its perimeter.
-
Mass:
The amount of matter in an object. Mass is different from
weight, which measures the force of gravity
acting on an object.
-
Temperature: The amount of warmness or coldness
in an object. The device used to measure temperature is a
thermometer. There are two systems for measuring,
both of which use degrees as the unit of
measure.
The first scale is measured in degrees Fahrenheit.
The range from freezing point to boiling point on this scale
is 32 to 212 degrees.
The other scale is measured in degrees Celsius.
Sometimes it is also referred to as the Centigrade
scale. The range from freezing point to boiling point on this
scale is 0 to 100 degrees.
-
Time can be defined in two ways. One is a measure of the period
between two events, or the period in which something happens.
The second definition is the precise moment determined by
a clock.
Time can be measured in several units. Refer to the timetable
to see the different ways time can be expressed.
One last thing to keep in mind about time is that we refer
to the time of day as a.m. (ante meridiem) or p.m. (post meridiem).
· a.m. refers to the hours after midnight and before
noon.
· p.m. refers to the hours after noon and before midnight.

- Volume
is the amount of space taken up by a three-dimensional object.
Volume often refers to liquid volume, which
is defined as the amount of space taken up by a liquid, which
spreads completely to fill its container.
