Unit Explanations
Pounds per Square Inchpsi
Source UnitPsi or 'pounds per square inch' is a unit used to measure pressure. It defines the pressure resulting from a force of one pound-force applied to an area of one square inch. As a non-SI unit, it is commonly used in the United States and other countries still employing the Imperial system. Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
Current Use
Today, psi is extensively used in various fields, particularly in the United States. It is prevalent in automotive applications, where it measures tire pressure, ensuring safety and performance. Additionally, psi is crucial in aerospace, measuring cabin pressure and hydraulic systems. In industrial settings, it is used for pressure gauges, compressors, and pneumatic tools. Despite the global trend towards SI units, psi's practical relevance maintains its usage in specific regions and industries.
Fun Fact
Psi is still a preferred unit in U.S. automotive manuals.
Millibarmbar
Target UnitThe millibar (mbar) is a metric unit of pressure defined as one-thousandth of a bar, where 1 bar is equivalent to 100,000 pascals. The millibar is commonly used in meteorology to report atmospheric pressure, providing a more manageable scale compared to the bar. It is defined as 100 pascals, making it convenient for understanding weather phenomena and pressure systems. The millibar is an important unit in various scientific and engineering fields, allowing for precise measurements in a compact form.
Current Use
The millibar is predominantly used in meteorology to report atmospheric pressure, helping meteorologists analyze weather patterns and predict climatic conditions. It is also utilized in various engineering applications, such as HVAC systems and aerodynamics, where precise pressure measurements are critical. While the pascal is the SI unit for pressure, the millibar remains popular in weather reporting and environmental studies.
Fun Fact
The millibar was first widely used in meteorological observations to standardize pressure readings across different regions.

Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
History & Origin
The psi unit emerged from the need to measure pressure in the Imperial system, prevalent in the United States and other regions before the widespread adoption of the metric system. It is a derivative unit representing the pressure exerted by a force of one pound-force on a square inch of surface area. The concept of pressure measurement has evolved over time, with psi becoming a standard term in industries reliant on precise pressure control.
Etymology: The term 'psi' stands for 'pounds per square inch,' combining 'pound,' a unit of force, and 'square inch,' a unit of area.

Millibar
pressure • Non-SI
Definition
The millibar (mbar) is a metric unit of pressure defined as one-thousandth of a bar, where 1 bar is equivalent to 100,000 pascals. The millibar is commonly used in meteorology to report atmospheric pressure, providing a more manageable scale compared to the bar. It is defined as 100 pascals, making it convenient for understanding weather phenomena and pressure systems. The millibar is an important unit in various scientific and engineering fields, allowing for precise measurements in a compact form.
History & Origin
The concept of the millibar emerged in the late 19th century as scientists and engineers sought a practical way to express atmospheric pressure. The bar itself was established as a unit of pressure in 1909 at the International Conference of Weights and Measures. The millibar was subsequently defined as one-thousandth of a bar, making it easier to express lower pressures encountered in meteorological contexts.
Etymology: The term 'millibar' is derived from the SI unit 'bar', which originates from the Greek word 'baros', meaning weight. The prefix 'milli-' signifies a factor of one-thousandth.
Current Use
The millibar is predominantly used in meteorology to report atmospheric pressure, helping meteorologists analyze weather patterns and predict climatic conditions. It is also utilized in various engineering applications, such as HVAC systems and aerodynamics, where precise pressure measurements are critical. While the pascal is the SI unit for pressure, the millibar remains popular in weather reporting and environmental studies.
💡 Fun Facts
- •The millibar was first widely used in meteorological observations to standardize pressure readings across different regions.
- •1 mbar is equivalent to 0.1 kPa, which makes it easier to relate to other pressure units.
- •The millibar is still used in aviation to denote atmospheric pressure levels at which aircraft operate.
