Measurement in Grade V

Hello friends, how are you all today? Previously we have discussed about properties of rational numbers ,Are you ready for today’s session?
Our today’s topic is an interesting topic of mathematics. Measurement is the topic what we are going to read. In measurement we include Types of Measurements,help with math measurements, Measurement Problems in grade V of andhra pradesh board of secondary education. So students let's start now.
Measurement is the process of calculating or determining result of quantities. When I was a kid and my teacher asked me first what you know about measurement. I always found difficulty to answer back. Let me tell you a fact that you also deal with measurement daily but the thing is that you are not aware of it.
When you said to one of your friend that you are taller than him and he claims the same than you both stood stand by each other or use a tape to determine who is taller.
That means you are calculating your height or we can say it as you are measuring your height.
We use some units to compute them. Like in our example the unit of height is inches or feet. Likewise unit of mass for example our weight is measured in kilograms. And time, you all are familiar with the unit of time. What it is? It is seconds, minutes or hours.
Now after knowing measurement we will move on to the types of measurements their units and measurement problems. In measurement problems we learn how to convert one unit into other.(want to Learn more about Measurement ,click here),

Let us discuss about mass measurement. Mass is the amount of material in an object that are not effected by        the environment.
Based on the International System (SI) the unit of mass is Kilogram often denoted as kg.
We have seven base measurements and kg is one of them.

Different units of mass and their conversion:
10 milligrams = 1 centigram
10 centigrams = 1 decigram
10 decigrams = 1 gram
10 grams = 1 dekagram
10 dekagrams = 1 hectograms
10 hectograms = 1 kilogram
1,000 kilograms = 1 metric ton













We generally say weight in place of mass. But weight and mass are two different quantities.
Mass is a measure that how much material some object can contain whereas  weight is the measure that how strongly gravity pulls some object.

Now we will go through time measurement:
To determine time we need some measurement unit. Based on the International System (SI) the unit of time is minutes. We also have second and hour etc to describe time.

Different units of time and their conversion:

1 minute = 60 seconds
1 hour = 60 minutes = 3600 seconds
1 day = 24 hours
1 week = 7 days
1 year = 365 days

Now I will tell you about volume measurement. Volume is the measure to compute the capacity of the object.
For example: How much a water bottle can contain is the capacity of that bottle.
Unit of volume is liter we often use lt instead of liter. Except liter we also have milliliter, centiliter etc units to measure volume.

Different units of volume and their conversion
1 milliliter = 0.001 liter
1 centiliter = 0.01 liter
1 deciliter = 0.1 liter
1 kiloliter = 1000 liters

We can also simplify this table as:
1000 milliliter = 1 liter
100 centiliter = 1 liter
10 deciliter = 1 liter

These all are some measurements, their types, and some measurement problems. Do refer some exercises on measurement and get perfect and if anyone want to know about Measures of central tendency/dispersion
then they can refer to internet and text books for understanding it more precisely. Read more maths topics of different grades such as Mean and median in Maths in the next session here.
