What is Millibars?
Millibars (mbar) is a unit of pressure. The millibar is a unit of pressure equal to 100 pascals or 0.1 kilopascals. It is one-thousandth of a bar, which is defined as exactly 100,000 pascals in the International System of Units (SI). The millibar is commonly used in meteorology to measure atmospheric pressure and is recognized under ISO standards for pressure units [iso-80000]. The bar and its subunit, the millibar, were introduced by the German meteorologist Heinrich von Helmholtz in the early 20th century. The millibar was adopted as a practical unit for meteorological pressure measurements before SI units were formalized [nist-sp-811]. Millibars remain widely used in weather reports and aviation worldwide, especially in countries like the United States, United Kingdom, and Australia. Meteorological agencies, including NOAA and the UK Met Office, use millibars alongside pascals for atmospheric pressure [nist-sp-811].
What is Pounds per Square Inch?
Pounds per Square Inch (psi) is a unit of pressure. Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch of area. It is defined as 1 psi = 6,894.76 pascals in the SI unit system [nist-si-guide]. Psi originated in English-speaking countries for engineering and industrial applications during the 19th century, formalized through American standards for pressure measurement [nist-si-guide]. Psi remains common in the United States, Canada, and the UK for tire pressure, hydraulic systems, and HVAC industries. It is also referenced in international engineering standards [nist-sp-811].
Common Misspellings
People often search for this conversion using these alternate spellings: milibars, milibars, millibar, milibar, pounds per square inch, pound per sq inch, psiin. All of these refer to the Millibars to Pounds per Square Inch conversion.
