How many inches of W.C. is 0.5 PSIG?

To convert PSIG (pounds per square inch gauge) to inches of water column (W.C.), it’s essential to understand the relationship between these two units of pressure.

1 PSIG is approximately equivalent to 27.7 inches of water column. Therefore, to find out how many inches of W.C. correspond to 0.5 PSIG, you would multiply 0.5 by 27.7.

Performing the calculation:

0.5 PSIG × 27.7 inches of W.C./PSIG = 13.85 inches of W.C.

Rounding this value gives us approximately 14 inches of W.C. Thus, when determining how many inches of water column correspond to 0.5 PSIG, the answer is indeed 14 inches of W.C. which confirms that it is the correct choice. This knowledge is critical in gas technician work to ensure safe and accurate pressure measurements in gas appliances.
