This means if you have a pressure gauge reading 1 inch per mercury, it can be further split up into 25.4 millimeters of mercury. One advantage of mm/hg is that it provides a high level of accuracy. A measurement of 15 mm/hg is just 0.59 in/hg, which is a rather arbitrary method to express pressure. The second advantage of using millimeters of mercury, is that it provides a solid range of integers to represent a relatively low pressure.
