Conversion of Units (length, weight)

Ginny is a great teacher

She gave a problem to her class to solve

She told them to find the total height of the flag post above the ground level

which means she asked the class to find the length of

After a while, a student said that the height of the flag post above ground level is

Then, everyone said the same answer

Ginny said that everyone has said the wrong answer

She said that since the length of the flag post is in and the rest in

So, we cannot add them as they are in different units

So, before we add we need to bring all the units into the same unit

So that we can add and find the height of the flag post above the ground level

Before we solve we should always check and convert everything to the same unit and then find the answer

So, let us see some basic conversions which will help you use and bring everything to the same unit

These are the basic conversions used in our daily lives

Now, let us come back to the problem again

Now, we need to calculate

So first, we convert everything into the same units

We know, So,

And, So,

So,

So, Ginny explained how to convert the length of one unit from another

She also said that the quantities we deal with are not only lengths or heights but also weights and mass

So, let us see the basic conversions of weights and masses too

In lengths, we deal with etc. But here we will deal with etc

These are the basic conversions we need to memorize which will help to bring them to a single unit

Let us work out an example to have a better understanding

Let us find in

We know So,

So,

Now, So,

So, we know how to convert the basic quantities of different lengths and weights
