Unit Explanations
Barbar
Source UnitThe bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.
Current Use
The bar is widely used in various fields including meteorology for atmospheric pressure, and in industries such as automotive and aviation for tire pressure and cabin pressure monitoring. It is especially favored in contexts where moderate pressures need to be measured with a single-digit number, avoiding the unwieldy values that would result from using pascals.
Fun Fact
The bar is almost exactly the atmospheric pressure on Earth at sea level.
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.

pressure • Non-SI
Definition
The bar is a metric unit of pressure, not part of the International System of Units (SI), but is commonly used in industry and meteorology. It is defined as exactly 100,000 pascals, which is slightly less than the average atmospheric pressure on Earth at sea level. One bar is equivalent to 0.987 atmospheres, 14.5038 pounds per square inch (psi), or 750.06 millimeters of mercury (mmHg). Although not an SI unit, it is accepted for use with the SI and is widely used due to its convenient size for many applications.
History & Origin
The bar as a unit of pressure was introduced in the early 20th century. It was created to provide a convenient metric unit for expressing pressures without having to resort to using large numbers, as can occur with the pascal. The bar was defined in 1909 by the International Union of Pure and Applied Chemistry (IUPAC) to be equivalent to 100,000 pascals, simplifying conversion with the SI system.
Etymology: The word 'bar' comes from the Greek word 'baros', meaning weight.
Current Use
The bar is widely used in various fields including meteorology for atmospheric pressure, and in industries such as automotive and aviation for tire pressure and cabin pressure monitoring. It is especially favored in contexts where moderate pressures need to be measured with a single-digit number, avoiding the unwieldy values that would result from using pascals.
💡 Fun Facts

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.
