What unit is used to measure deep vacuum?

Explanation:
Deep vacuum is all about extremely low pressure, so you need a unit that can express tiny amounts of pressure with good precision. Microns of mercury fit that need perfectly: a micron of Hg is one-thousandth of a Torr, giving a fine-grained scale for ultra-low pressures. This precise scale is why deep vacuum measurements are commonly read in microns rather than in larger units like inches of mercury or Torr. While Pascals are the SI unit of pressure and can describe these values, microns of Hg provide the traditional, practical granularity used in vacuum work, especially for the very low pressures encountered in deep vacuum.
