2. The advent of technology has
allowed people to use
measuring devices to
accurately measure distance. In
the English System of
measurement, the units for
distance that are commonly
used are yard, foot, inch, and
mile.

4. Most common tool used
for measuring short
distances. It is also used
to check straight line and
symmetry. It is usually
made up of plastic, wood,
or metal.
RULER OR STRAIGHT EDGE
RULE

6. It is a measuring stick that
is one meter long. It is
marked off in centimeters
and millimeters. Just like
a ruler, it is usually made
up if plastic, wood, or
metal.
METERSTICK

8. It is a measuring tool that can
be rolled out and carried along
easily. It has a bent tab at the
end which is helpful in
hooking around surfaces. This
allows accurate measurement
of distances on surfaces or
any vertically inclined areas
such as a wall.
TAPE MEASURE
9.
10. It is also called as surveyor’s
wheel, is used for measuring
extreme long distances, such
as the size of a building lot or
the perimeter of a big area. It
has a calibrated wheel
attached to the handle.

11. It is measuring device used
to measure arbitrary curved
lines. This instrument is
commonly used to measure
line features on maps, such
as the lengths of roads and
rivers.
CURVIMETER
12.
13. It is another measuring
device. It has two hinged legs
that resemble that of a
compass. It is used to
measure distance between
two opposite sides of an
object.
CALIPER
14.
15. YARDSTICK
It is also used to measure
length or distance. It is like a
meterstick, but instead of one
meter, it can only measure up
to one yard. It is typically
divided into inches.
Yardsticks are often made of
wood or metal. They are also
thin and rectangular.
16.
17. It can now be used to
measure distances with the
integration of technology.
These devices emit laser
pulses in a particular object
and measure the time it
takes for the beam to go
back.
