Measurement Glossary
Angle: The figure formed by two rays
diverging from a common point, expressed in degrees.
Area: The extent of a planar region or of the surface of a
solid measured in square units.
Circumference: The boundary
line of a circle.
Coordinate plane: A plane spanned by
the x-axis and y-axis in which the coordinates of a point
are its distances
from two intersecting perpendicular axes; also called
Cartesian
plane.
Cube: A regular solid having six congruent
square faces.
Cubic measures: A unit, such as a cubic
foot, or a system of units used to measure volume or
capacity.
Congruent: Corresponding in character
or kind; the same.
Customary system: A system of weights
and measures based on the foot, pound, second and pint.
Foot: A unit of length in the U.S. Customary and British Imperial
systems equal to 12
inches (0.3048
meter)
Pound: A unit of weight equal to
16 ounces (453.592 grams)
Length: The measurement of the
extent of something along its greatest dimension
Second: A unit of time equal to the 60th part of a minute
Pint: A unit of volume
or capacity in the U.S. Customary System, used
in liquid
measure, equal
to 1⁄8 gallon
or 16 ounces (0.473 liter)
Cylinder: A solid bounded by two parallel
planes and such a surface,
especially
such a surface
having a
circle as
its end pieces.
Estimation: An
opinion or a judgment (an educated guess).
Linear measure: A unit or system of units for measuring length.
Measurement: The act or process of measuring; a figure, extent
or amount
obtained by
measuring.
Metric system: A decimal system of units based on
the meter
as a unit
length,
the kilogram
as a unit
mass
and the second
as a unit time.
Meter: The international standard unit of length,
approximately
equivalent to 39.37
inches

of volume equal to 1000 cubic
centimeters or one
cubic
decimeter
(1.0567

unit of mass equal to
one thousandth
(10-3)
of a
kilogram
Perimeter: The length of the boundary
of
a closed
curve
bounding a plane
area.
Prism: A
solid figure whose
bases or ends
have the
same size and
shape and
are parallel
to
one another,
and each
of whose sides
is a parallelogram.
Protractor: A semicircular
instrument
for
measuring
and constructing
angles.
Square: A plane figure
having
four equal
sides and
four equal
angles.
Square
measure: A system
of units
used
to measure
areas.
Surface
area: The
extent of a
two-dimensional
surface
enclosed
within
a boundary.
Temperature: The
degree
of
hotness
or
coldness
of
a
body or
environment.
Fahrenheit: A temperature
scale that
registers the
freezing point
of water
as 32
degrees and
the boiling
point as
212 degrees
Celsius: A temperature
scale that
registers the
freezing point
of water
as 0
degrees and
the boiling
point as
100 degrees
Weight: A measure
of the
heaviness of
an object;
a unit
measure of
gravitational force.
Width: The measurement
of the
extent of
something from
side to
side.
Volume: The amount
of space
occupied by
a three-dimensional
object or
region of
space, expressed
in cubic units. |
