Unit Explanations
PascalPa
Source UnitThe pascal (Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. It is defined as one newton per square meter. In other words, it is the pressure exerted by a force of one newton acting uniformly over an area of one square meter. The pascal is a crucial unit in engineering, physics, and meteorology, providing a standard measure for atmospheric pressure, material strength, and force distribution. It allows for consistent and comparable measurements across various scientific and industrial fields.
Current Use
The pascal is widely used in various fields to measure pressure and stress. In meteorology, it is used to express atmospheric pressure, often in the form of hectopascals (hPa). In engineering, it helps evaluate the strength of materials and structures. The unit is also crucial in fluid mechanics, where it is used to determine fluid pressure in pipes and vessels. The pascal's versatility makes it a fundamental unit in both scientific research and practical applications, especially where precise pressure measurements are critical.
Fun Fact
The pascal is named after Blaise Pascal, who made significant contributions to the understanding of fluid pressure.
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.
Convert Pascal to Millibar (Pa to mbar)
Convert Pascals (Pa) to Millibars (mbar). While Pascals are the correct SI unit, 'millibar' remains deeply entrenched in maritime and aviation weather forecasts. Converting Pa to mbar makes the data readable for sailors and pilots.
Divide Pascals by 100. For example, 100,000 Pa = 1000 mbar.

Definition
The pascal (Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. It is defined as one newton per square meter. In other words, it is the pressure exerted by a force of one newton acting uniformly over an area of one square meter. The pascal is a crucial unit in engineering, physics, and meteorology, providing a standard measure for atmospheric pressure, material strength, and force distribution. It allows for consistent and comparable measurements across various scientific and industrial fields.
History & Origin
The pascal was named in honor of Blaise Pascal, a French mathematician, physicist, and inventor known for his contributions to fluid mechanics and the study of pressure. The unit was officially adopted as the SI unit for pressure in 1971, although the concept of pressure itself dates back to early scientific studies of fluids and gases. The pascal provided a standardized way to measure pressure, replacing a variety of non-standard units previously in use across different regions and industries.
Etymology: The term 'pascal' is derived from the name of Blaise Pascal.

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.
