Millimeters and inches measure length. Millimeters are used in the metric system, while the inch is used in the imperial system. When converting between millimeters and inches, you need to know that there are 25.4 mm per inch. For example, if you were gi
meaning that system has either lower or higher barometric pressure than the surrounding areas. Many barometers use mercury to measure barometric pressure. Since the chemical symbol for mercury is Hg, readings of barometric pressure are often reported in inches of mercury (in/Hg) or millimeters of ...
