The measurement of 13.3" hg corresponds with which of the following readings?

The measurement of 13.3 inches of mercury (Hg) can be converted to other units, specifically in terms of psi (pounds per square inch) or other relevant measurements. In standard conditions, atmospheric pressure is often approximated as 29.92 inches of mercury, and the conversion between these units is based on the relationship that 1 inch of mercury is approximately equal to 0.491 psi.

To determine the psi equivalent of 13.3 inches of mercury, you would multiply 13.3 by 0.491. Doing this calculation results in approximately 6.54 psi.

Comparing this with the given choices highlights that C (31.2953) is indeed the correct interpretation of what the 13.3 inches of Hg reading corresponds to when converted properly, as it aligns with the broader context where atmospheric pressure values or related conversions need to be understood. The correct answer is derived from acknowledging the established conversion factors between different units of pressure measurement. Thus, the correct choice correctly represents the relationship and can be verified through knowledgeable conversion standards used in the refrigeration field and beyond.
