Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Can someone explain where the 32.2 is coming from please
A manometer consists of a tube of 0.5 inch in the inner diameter and an amount of mercury (SG Hg =13.55). On one side of the tube, oil (SG=1.4) was trapped, a bubble formed, and the fluid inside was stationary. The volume of the oil was 0.6 in^3 and the volume of the air was 0.2 in^3. Now, the oil and bubble are removed. The pressure change across the air bubble is negligible and any curvature on the bubble surface can be neglected in calculating the volumes. Determine how much the mercury height rises (i.e. h 4 -h 2 ).
