(b)
In some cases, gages reading in pounds per square inch are
used for determining pressures while standard characteristics
are given in inches of mercury or inches of water. It is extremely
important that the scale of such a gage be of low range and
finely divided if accuracy is desired. This is especially true of a
gage reading in psi, the reading of which is to be converted to
inches of water. The following conversion factors may be
helpful.
Inches of water = psi x 27.7 inches
Inches of mercury = psi x 2.04 inches
