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.
PetapascalPa
Target UnitThe petapascal (Pa) is a unit of pressure in the International System of Units (SI), representing one quadrillion pascals (1 Pa = 10^15 Pa). It measures the force applied per unit area, where one pascal is defined as one newton per square meter. The petapascal is predominantly used in scientific and industrial contexts where extremely high pressures are involved, such as in material science, geology, and engineering applications. This unit is vital for quantifying pressures beyond the range of ordinary units, providing clarity in calculations and comparisons.
Current Use
The petapascal is primarily utilized in research and industry sectors where extreme pressures are encountered, such as in deep-sea exploration, high-energy physics, and materials testing. It serves as a standard unit for reporting pressures in scientific literature and engineering specifications. Due to the increasing complexity of modern experiments and technologies, the petapascal allows for more accessible communication of pressure values in these fields.
Fun Fact
The petapascal is equivalent to the pressure exerted by a car sitting on a single square meter of ground.

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.

History & Origin
The petapascal originates from the pascal, which was named after Blaise Pascal, a French mathematician, physicist, and inventor known for his contributions to fluid mechanics and pressure measurement. The pascal was adopted as the SI unit of pressure in 1960, forming part of the metric system. The prefix 'peta-' denotes a factor of 10^15, which was established in the International System of Units (SI) in the 1970s to accommodate the need for larger units in scientific measurements.
Etymology: The term 'pascal' is derived from the name of Blaise Pascal, while 'peta' comes from the Greek word for 'five', indicating a power of 15 (10^15).
Current Use
The petapascal is primarily utilized in research and industry sectors where extreme pressures are encountered, such as in deep-sea exploration, high-energy physics, and materials testing. It serves as a standard unit for reporting pressures in scientific literature and engineering specifications.
