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.
Dyne per Square Centimeterdyn/cm²
Target UnitThe dyne per square centimeter (dyn/cm²) is a unit of pressure derived from the CGS (centimeter-gram-second) system. It defines the force of one dyne applied uniformly over an area of one square centimeter. In SI units, 1 dyn/cm² is equivalent to 0.001033227 kilopascals (kPa). It is used in various scientific and engineering contexts to express pressures, particularly in fields dealing with small forces and areas. The dyne itself is a force that accelerates a mass of one gram at one centimeter per second squared.
Current Use
The dyne per square centimeter is primarily used in fields such as physics, engineering, and material science, especially in studies involving small-scale pressures and forces. While the SI unit of pressure (pascal) is more prevalent, the dyne/cm² is still used in specific contexts where historical measurements may persist. Laboratories and research institutions may employ this unit when dealing with detailed mechanical analyses or experiments involving fluids and gases at low pressure levels.
Fun Fact
The dyne is related to the force required to accelerate a mass of one gram at one centimeter per second squared.

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
- •The bar is almost exactly the atmospheric pressure on Earth at sea level.
- •The unit 'bar' is not an SI unit, but it's accepted for use with SI due to its practicality.
- •The word 'barometer', an instrument for measuring atmospheric pressure, shares its root with the unit 'bar'.

Dyne per Square Centimeter
pressure • Non-SI
Definition
The dyne per square centimeter (dyn/cm²) is a unit of pressure derived from the CGS (centimeter-gram-second) system. It defines the force of one dyne applied uniformly over an area of one square centimeter. In SI units, 1 dyn/cm² is equivalent to 0.001033227 kilopascals (kPa). It is used in various scientific and engineering contexts to express pressures, particularly in fields dealing with small forces and areas. The dyne itself is a force that accelerates a mass of one gram at one centimeter per second squared.
History & Origin
The dyne as a unit of force was first defined in the late 19th century as part of the CGS system. It was derived to facilitate calculations in mechanics where small forces were common, especially in physics and engineering. The dyne per square centimeter emerged as a practical unit for pressure in contexts where pressure differences were measured in smaller scales, leading to its adoption in various scientific applications.
Etymology: The term 'dyne' comes from the Greek word 'dynamis', meaning 'force' or 'power'. The 'centimeter' part of the unit name derives from the Latin 'centum', meaning 'hundred', and 'metrum', meaning 'measure'.
Current Use
The dyne per square centimeter is primarily used in fields such as physics, engineering, and material science, especially in studies involving small-scale pressures and forces. While the SI unit of pressure (pascal) is more prevalent, the dyne/cm² is still used in specific contexts where historical measurements may persist. Laboratories and research institutions may employ this unit when dealing with detailed mechanical analyses or experiments involving fluids and gases at low pressure levels.
💡 Fun Facts
- •The dyne is related to the force required to accelerate a mass of one gram at one centimeter per second squared.
- •In terms of SI units, 1 dyn/cm² is equivalent to approximately 0.001033227 kPa, illustrating the small scale of the unit.
- •The dyne per square centimeter is often used in historical texts, making it a classic reference point for researchers in material science.
