1st Class Mathematics Measurement Length, Weight and Capacity Measurement

MEASUREMENT

Measurement                             

Measurement means determining the size, length, distance, height etc. of objects, place etc. The kilometre, metre, centimetre, inches and foot are the units of distance and length. While kilometre and metre are used for long and average distances, and length, centimetre, inches and foot are used to measure short distances.

What is Length and Breadth?                                         

Length is the longer dimension of an object, while breadth is the dimension from side to side.

Let's see the picture given below:                                            

Look at the following:

[1] kilometer = [1000] meters

[1] meter = [100] centimeters.

Therefore,

[2] meters = two [100] centimeters

[3] meters = three [100] centimeters and the process goes. on.

Again,

[1] foot = [12] inches.

Therefore,

[2] feet = two [12] inches = [24] inches.

[3] feet = three [12] inches = [36] inches.

Points to remember,

Short forms

Kilometre = [km],

Metre = [m],

Centimetre = [cm]

•          Example:

How many kilometres are there in one 1000 metres?

(a) 4                                                                  (b) 1

(c) 3                                                                  (d) 5

(e) None of these

Answer (b)

Explanation: (b) is correct because [1] km = one [1000] metres.

Note:

[km] > [m] > [cm]

\[Foot>Inch>Cm\]
