### Theory:

In our daily life we used to calculate the physical quantity in units, like meter centimeters, but do you know how to convert those units to others? Lets learn it.

Unit conversion:

To convert the millimeter to centimeter divide the given number by $$10$$, and to convert the quantity from centimeter to millimeter multiply the number by $$10$$.

To know more about the conversion of units clearly observe below table.
