Tips: Units of Vacuum Pressure Meter

• Pascal (Pa): The SI unit of pressure, with 1 Pa = 1 N/m². Often used in high and ultra-high vacuum systems.
• Torr: Equal to 1/760 of an atmosphere, or about 133.32 Pa. Commonly used in vacuum technology.
• Millimeters of mercury (mmHg): Similar to Torr, with 1 mmHg = 133.322 Pa. Used in medical and laboratory applications.
• Bar: Industrial unit where 1 bar = 100,000 Pa. Millibars (mBar) are common in vacuum systems.
• Inches of mercury (inHg): Used in U.S. vacuum systems, with 1 inHg = 3,386 Pa.
• Micron (µm): Equal to 0.001 mmHg or 0.133322 Pa, often used for measuring high vacuum.
