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.
Microbarµbar
Target UnitThe microbar (symbol: µbar) is a non-SI unit of pressure that is defined as one millionth of a bar. A bar is a metric unit of pressure defined as exactly 100,000 pascals (Pa). Therefore, one microbar is equivalent to 0.1 pascals. The microbar is commonly used in meteorology and various scientific fields to measure atmospheric pressure, especially when the pressure values are very low. It allows for easier reporting and understanding of pressure variations in these contexts.
Current Use
Today, the microbar is primarily used in meteorology, oceanography, and various scientific research fields. It is particularly relevant in contexts where atmospheric pressure is measured, such as weather forecasting, climate studies, and aviation. The microbar helps scientists and engineers monitor pressure changes in various environments, enabling better understanding and predictions of weather patterns.
Fun Fact
The microbar is often used in conjunction with other pressure measurements, such as millibars and pascals.

pressure • SI Unit
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.

Microbar
pressure • Non-SI
Definition
The microbar (symbol: µbar) is a non-SI unit of pressure that is defined as one millionth of a bar. A bar is a metric unit of pressure defined as exactly 100,000 pascals (Pa). Therefore, one microbar is equivalent to 0.1 pascals. The microbar is commonly used in meteorology and various scientific fields to measure atmospheric pressure, especially when the pressure values are very low. It allows for easier reporting and understanding of pressure variations in these contexts.
History & Origin
The concept of pressure units dates back to early studies in fluid mechanics and thermodynamics. The bar was introduced in the 19th century by the French engineer and physicist Henri Poincaré, who proposed it as a practical unit for measuring atmospheric pressure. The microbar emerged as a convenient subdivision of the bar for applications requiring finer resolution of pressure measurements.
Etymology: The term 'microbar' combines the Greek prefix 'micro-' meaning 'small' with 'bar', a word derived from the Latin 'barra' meaning 'bar, rod'.
Current Use
Today, the microbar is primarily used in meteorology, oceanography, and various scientific research fields. It is particularly relevant in contexts where atmospheric pressure is measured, such as weather forecasting, climate studies, and aviation. The microbar helps scientists and engineers monitor pressure changes in various environments, enabling better understanding and predictions of weather patterns.
💡 Fun Facts
- •The microbar is often used in conjunction with other pressure measurements, such as millibars and pascals.
- •One standard atmosphere (1 atm) is equivalent to 1013.25 hPa, which is equal to 101,325 µbar.
- •The microbar is particularly useful for measuring pressure changes over short time spans, making it ideal for meteorological studies.
