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.
TorrTorr
Target UnitThe torr is a unit of pressure that is defined to be exactly 1/760 of one standard atmosphere (atm). It is named after the Italian physicist Evangelista Torricelli, who invented the barometer in 1643. The torr is commonly used in various scientific fields, particularly in meteorology, physics, and vacuum technology. One torr is equivalent to 133.322 pascals (Pa), making it a convenient unit for expressing low pressures. The unit is widely utilized in laboratory settings and industrial applications where precise pressure measurements are essential.
Current Use
Today, the torr is widely used in laboratories and industrial settings for measuring pressure in vacuum systems and other applications. It is favored for its convenience in expressing low pressures, particularly in scientific research where high precision is required. The torr is also utilized in meteorology to report atmospheric pressure measurements, enabling meteorologists to forecast weather patterns effectively. Although the pascal has become the SI standard unit for pressure, the torr remains prevalent in several fields due to its historical significance and ease of use.
Fun Fact
The torr is defined based on the atmospheric pressure at sea level, which is why it is closely related to the standard atmosphere.

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'.
