MBAR to Torr Converter: Convert Millibar to Torr
Use this convenient tool to convert pressure values from millibar (mbar) to torr. Ideal for vacuum systems, scientific instrumentation, and pressure monitoring.
Understanding the Conversion from Millibar (mbar) to Torr
Pressure plays a critical role in many scientific, industrial, and environmental systems. Among the many units used to measure pressure, millibar (mbar) and torr are frequently encountered in meteorology, vacuum systems, and laboratory settings. Converting between these two units allows for greater flexibility and compatibility across different instruments and standards. This page provides an accurate and reliable tool to convert millibar to torr, along with detailed information about both units and their applications.
What Is a Millibar (mbar)?
The millibar is a unit of pressure equal to 100 pascals (Pa). While not an official SI unit, it is widely accepted in fields such as meteorology and aviation. Atmospheric pressure at sea level is commonly quoted as approximately 1013.25 mbar. Its practical size and historical usage make it ideal for expressing environmental pressures and barometric data.
What Is a Torr?
The torr is a unit of pressure based on an absolute scale, defined as exactly 1/760 of standard atmospheric pressure. This means that 1 atm = 760 torr. The torr is named after Evangelista Torricelli, an Italian physicist and mathematician who invented the barometer. Torr is especially prevalent in vacuum technology, where precision measurement is required.
Conversion Formula
Torr = mbar × 0.750062
Example: 1000 mbar × 0.750062 = 750.06 torrMBAR to Torr Conversion Table
