Conversions
We have learned to convert the units from higher to lower and vice-versa in the previous class.
Let us revise the concepts of conversion once again before we move further.

We can convert one unit of measurement to another with the help of following diagrams.
To convert from lower units to higher units, we divide by 10 or 100 or 1000.

÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10 ÷ 10
