What is Measurement? 

  • Measurement is a method by which the properties of an object can be determined by only comparing them to a standard quantity. 

  • The most basic metric for expressing any quantity of objects, things, or events is measurement.

Measurement Units 

For different types of measurements, we have different units of measurement. Different units of measurement are given below.

  • Length: Units of measuring length are metres, centimetres, millimetres, kilometres etc. 

  • Time: Seconds, minutes, hours, days, weeks, months, years etc are the units used to measure length. 

  • Weight: Units such as grams, kilograms, and tons are used to measure or express the weights of different objects. 

  • Volume: To measure the volume of certain quantities units such as litres, millilitres etc are used. 

  • Temperature: Major units used to measure the temperature of certain objects are centigrade and Fahrenheit.

  • It should be noted that it is possible to convert one unit from another

Metric System 

  • The standard unit of length is the metre in the metric system. Similarly, the standard unit of mass is a kilogram and the standard unit of volume or capacity is a litre. 

  • 100 equal parts of the centimetre successfully make a metre. 

  • When one centimetre is divided into 10 equal parts it is called millimetres. 

  • 1 cm = 1/100 m = 0.01 m 

  • 1 m = 100 cm 

  • 1cm = 10mm 

  •  1mm = 1/10 cm = 0.1 cm

Changing the Metric Unit of Length 

Metric unit of length chart

  • Observe the above-mentioned metric chart. It is clearly evident that when we move from one metric unit to another to the right, the value of the metric unit becomes ten times smaller, which is one-tenth. 

  • When we move from one metric unit to another to the left in the metric chart, the value of the metric unit becomes ten times bigger.

  • Considering the above two statements these are the conversion for metres as the basic unit of length. 

  • 1 Decameter (dam) = 10 times metre 

  • 1 Hectometer (hm) = 100 times metre

  • 1 Kilometre (km) = 1000 times metre

  • 1 Decimeter (dm) = 1/10 of metre

  • 1 centimetre (cm) = 1/100 of metre

  • 1 millimetre (mm) = 1/1000 of metre

Solved Question

1. Sara purchased 40 m 200 cm long rope and Jain purchased 16 m 370 cm long rope. The total length of the ropes which is purchased by both of them is? 

Ans: Given, 

The length of rope purchased by Sara = 40 m 200 cm

The length of rope purchased by Jain = 16 m 370 cm 

We know that 1 m = 100 cm or 1 cm = 0.01 m 

In this problem, we just have to add both lengths.  

Now the total length of the rope purchased by both = 40 m 200 cm + 16 m 370 cm  = 56 m 570 cm

2. Ronny wants brand new clothes for Christmas so he visits a tailor. He agrees to stitch clothes and says to Rony that it would take 1 m 235 cm of cloth to make the shirt and 2 m 105 cm to make trousers. What is the total length of cloth that is used by the tailor to make a shirt and trousers? 

Ans: The total length of cloth required to make a shirt = 1 m 235 cm

The total length of cloth required to make trousers =  2 m 105 cm 

We know that 1 m = 100 cm or 1 cm = 0.01 m 

In this problem, we just have to add both lengths.  

Total length = 1 m 235 cm + 2 m 105 cm  = 3 m 340cm 

The Capacity of a Liquid 

  • The quantity or the volume of a liquid is measured in the units of capacity. 

  • A litre is a unit used to measure bigger quantities

  • Millilitres are used to measure smaller quantities. 

  • 1litre = 1000 millilitre and 1 millilitre = 0.001 litre.

Conversion of Litres Into Millilitres 

  • To convert litres into millilitres we just have to multiply the number of litres by 1000. 

  • For example, to convert 9 L 650 mL into mL we have to multiply 9 L by 1000 mL Hence, 

            = (9 x 1000) mL + 650 mL = 9650 mL.

Solved Example

1. What are the different ways to add up I litre? 

Ans: We know that 1L = 1000 mL. Thus keeping this in mind we have to add all the millilitres to make sure it gives the sum as 1000. Here are a few of the additions possible.

  • 500 mL + 500 mL = 1 L 

  • 450 mL + 550 mL =  1 L 

  • 400 mL + 350 mL + 250 mL = 1 L 

  • 800 mL + 200 mL =  1 L 

  • 100 mL+ 200 mL + 300 mL + 400 mL =  1 L 

  • 750 mL + 150 mL + 100 mL =  1 L 

Students can add and make any changes but please make sure that the sum should add up and must be equal to 1000 mL 

2.  Adithya is using a small bottle to fill a large 2-litre bottle. He poured 4 small bottles to completely fill the 2-litre bottle. How much water does his small bottle hold? 

Ans:  It is mentioned  that Adithya  poured  4 small bottles of water to fill a 2-litre bottle 

We know that 1 L = 1000 mL 

2 L = 2000 mL

4 small bottles = 2000/ 4 = 500 mL 

So it is clear that his small bottles can hold upto 500 mL of water. 

3. Leela has to pour 5 times through her small water bottle to fill a large 1-litre bottle. How much water does a small water bottle of Leela hold? 

Ans:  It is given that Leela has to pour 5 times to fill the 1-litre bottle. 

We know  that 1 L = 1000 mL 

Hence big bottle capacity is  1000 mL.

As Leela used 5 bottles to fill 1 litre bottle ,

Small bottle capacity = 1000/ 5 = 200 mL 

Therefore the capacity of each smaller bottle is 200 mL and Leela’s every small bottle can hold up to 200 mL.

4. Neetu has to take 3 injections a day for 5 days. One injection gives 5 mL of the medicine to your body.

(a) How much medicine will she need for one day?

(b) How much medicine in all for 5 days?

Ans:    From the given information, 

(a) One injection contains = 5 mL of medicine

The doctor advised her to take 3 injections a day 

Therefore , 5 mL x 3 = 15 mL of medicine

Hence for one day, Neetu needs 15 mL of medicine.

(b) The amount of medicine Neetu is getting in a day = 15 mL 

Quantity of medicine for 5 days = 15 mL x 5 = 75 mL 

Therefore she would need 75 mL of medicine for 5 days. 

5. Amina’s water bottle holds one litre of water. She drank 250 mL of water and her friend Govind drank 150 mL. How much water is left in her bottle?

Ans:  It is given that the total water Amina’s bottle holds = 1 litre = 100 mL 

To find the total water left in the bottle we first have to know the amount of water drank.

Total water drank = Water consumed by Amina + Water consumed by Govind 

Total water drank =  230 mL + 150 mL = 400 mL 

Therefore , water left in Amina’s bottle = 1000 mL - 400 mL = 600 mL. 

6. Yusuf runs a tea shop. For making a glass of tea he uses 20 mL of milk. Yesterday he made 100 glasses of tea. How much milk did he use?

Ans:  It is given that Yusuf has a tea stall 

To make one glass of tea the amount of milk Yusuf uses is 20 mL.

Therefore to make 100 glasses of tea, the amount of milk used will be

= 20 mL x 100 = 2000 mL

Practice Questions. 

1. Radha’s grandma was not well. The doctor gave her a bottle with 200 mL of medicine. She has to take the medicine every morning for 10 days.

How many millilitres of medicine does she have to take every morning? ________

Ans: Radha’s grandma has to take 20 mL of medicine every morning. 

Hint: To solve this problem, students have to know the capacity of the liquid concept.

2. Anand bought 7 L 650 mL milk from one dairy and 9L 250 mL from another diary. How much milk did he buy in total? 

Ans: A total of 17L 900 mL was bought by Anand from both the diaries. 

Hint: To solve this problem, students should know the concept of how to add litres and millilitres.
