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.
Kilogram-force per square centimeterkgf/cm²
Target UnitKilogram-force per square centimeter (kgf/cm²) is a unit of pressure defined as the force of one kilogram-force acting on an area of one square centimeter. It is a non-SI unit that expresses pressure in terms of the gravitational force exerted by a mass of one kilogram at standard gravity (9.80665 m/s²). The unit is commonly used in various engineering and scientific applications to quantify pressure in hydraulic systems, material testing, and other areas where pressure measurement is critical. One kgf/cm² is equivalent to 98,066.5 pascals (Pa).
Current Use
Kilogram-force per square centimeter is widely used in engineering, particularly in the fields of hydraulics and materials science. It provides a practical means for engineers and scientists to convey pressure measurements in a manner that is easily understandable and relatable, especially in applications involving pressure testing of materials or hydraulic systems. Despite the global shift towards SI units, kgf/cm² remains popular in industries like automotive, construction, and manufacturing.
Fun Fact
1 kgf/cm² is equivalent to approximately 98.0665 kPa, emphasizing the difference between traditional and SI units.

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'.

One kgf/cm² is equivalent to 98,066.5 pascals (Pa).
History & Origin
The concept of measuring pressure dates back to the development of hydraulics in ancient civilizations. The kilogram-force unit originated in the 19th century as engineers sought to quantify the force that gravity exerts on a mass. The definition was formalized with the establishment of the metric system, which aimed to standardize measurements across various scientific disciplines.
Etymology: The term 'kilogram-force' combines the metric unit 'kilogram,' representing mass, with 'force,' which in this context refers to the gravitational force exerted by that mass.
Current Use
Kilogram-force per square centimeter is widely used in engineering, particularly in the fields of hydraulics and materials science. It provides a practical means for engineers and scientists to convey pressure measurements in a manner that is easily understandable and relatable, especially in applications involving pressure testing of materials or hydraulic systems. Despite the global shift towards SI units, kgf/cm² remains popular in industries like automotive, construction, and manufacturing.
💡 Fun Facts
- •1 kgf/cm² is equivalent to approximately 98.0665 kPa, emphasizing the difference between traditional and SI units.
- •The kilogram-force is often used in Asian and Latin American countries, where kgf/cm² is still commonplace in engineering.
- •Despite being a non-SI unit, kgf/cm² is sometimes preferred in industry due to its historical context and ease of use.
