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.
Inch of Water (4°C)inH2O
Target UnitThe inch of water (4°C) is a non-SI unit of pressure defined as the pressure exerted by a column of water 1 inch high at a temperature of 4 degrees Celsius, where water reaches its maximum density. This unit is commonly used in various engineering applications, particularly in HVAC systems, to measure pressures in fluid systems. It is approximated as 0.0361 psi, serving as a practical measurement for pressure in systems where water is the working fluid.
Current Use
Today, the inch of water is widely used in various industries such as HVAC, plumbing, and meteorology. It serves as a standard reference for measuring low pressures in systems where water is the working fluid. Engineers and technicians frequently use this unit for calibrating instruments and ensuring efficient system performance, particularly in contexts where water pressure is critical.
Fun Fact
The inch of water is often used in barometric pressure measurements in meteorology.

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.

Inch of Water (4°C)
pressure • Non-SI
Definition
The inch of water (4°C) is a non-SI unit of pressure defined as the pressure exerted by a column of water 1 inch high at a temperature of 4 degrees Celsius, where water reaches its maximum density. This unit is commonly used in various engineering applications, particularly in HVAC systems, to measure pressures in fluid systems. It is approximated as 0.0361 psi, serving as a practical measurement for pressure in systems where water is the working fluid.
History & Origin
The inch of water has its roots in the traditional measurement systems originating from ancient civilizations, where pressure was often gauged based on the height of fluid columns. The specific reference to 4°C is due to the unique properties of water at this temperature, where it achieves maximum density. This measurement has been standardized in various contexts to facilitate fluid dynamics calculations and engineering applications.
Etymology: The term 'inch' comes from the Latin word 'uncia' meaning 'one-twelfth,' indicating its relation to the foot. 'Water' indicates the fluid medium being measured, while '4°C' specifies the temperature for precise density.
