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.
MillipascalmPa
Target UnitThe millipascal (mPa) is a metric unit of pressure defined as one-thousandth of a pascal (Pa). It is used to express small pressure values in a variety of scientific and engineering applications. The pascal itself is defined as one newton per square meter (N/m²), making the millipascal equal to 0.001 N/m². This unit is particularly useful when dealing with low-pressure situations, such as atmospheric measurements, fluid dynamics, and various industrial applications. The millipascal is commonly used in fields where precise pressure measurements are critical.
Current Use
Today, the millipascal is widely used in industries such as meteorology, engineering, and manufacturing. It is particularly common in the calibration of pressure measurement instruments, where small pressure variations need to be detected accurately. Laboratory settings often utilize millipascal measurements when dealing with gases and liquids under low-pressure conditions.
Fun Fact
The millipascal is often used in meteorology to report small changes in atmospheric pressure.

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 millipascal is commonly used in fields where precise pressure measurements are critical.
History & Origin
The pascal was named after Blaise Pascal, a 17th-century French mathematician, physicist, and inventor who made significant contributions to fluid mechanics and pressure. The millipascal emerged as a derived unit to facilitate measurements in scenarios where the pascal unit was too large, allowing for easier reporting and calculation in scientific and engineering contexts.
Etymology: The term 'millipascal' combines the prefix 'milli-', meaning one-thousandth, with 'pascal', derived from the name of Blaise Pascal.
