Many countries use only the metric system of measurement. In the United States, however, we use measurements in both metric units and customary units. Sometimes we need to convert between the two systems.

The table below shows equivalences between customary and metric systems. You can use these equivalences to convert a measurement in one system to a measurement in the other system.

The systems are not related so the conversions are approximate, as indicated by the symbol ≈.

Yes,

Explanation:
The centimeters in the numerator of the conversion factor
become the units of the final answer. Because the numerator and
denominator of a conversion factor are equal,
multiplying any quantity by a conversion factor is
equivalent to multiplying by the number 1 and
so does not change the intrinsic value of the quantity.

$$\frac{2}{9}$$ = $$\frac{63 X 2}{4 X 9}$$ =
$$\frac{7}{2}$$ as numerator is greater than denominator
we write in mixed fraction as 3$$\frac{1}{2}$$.
