What is 0.5 psig in "inches W.C."?

7" W.C.
21" W.C.
14" W.C.
3.5" W.C.

The correct answer is: 14" W.C.

To convert psig (pounds per square inch gauge) to inches of water column (inches W.C.), it's essential to know the conversion factor between the two units. 1 psig is equivalent to approximately 27.7 inches of water column. Therefore, to find out what 0.5 psig is in inches W.C., you multiply 0.5 by the conversion factor: 0.5 psig × 27.7 inches W.C./psig = 13.85 inches W.C. When rounding this figure, it equates closely to 14 inches W.C. Thus, the conversion reflects the relationship between pressure measurement in pounds per square inch and inch water column, enabling professionals to understand and apply the correct pressure readings in gas fitting contexts. This knowledge is crucial for ensuring installations are both safe and compliant with relevant standards.
