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.
Ton Force per Square Inchtf/in²
Target UnitThe ton force per square inch (tf/in²) is a non-standard unit of pressure that denotes the pressure exerted by a force of one short ton (2,000 pounds) distributed evenly over an area of one square inch. In SI terms, this value is equivalent to 2,000 pounds-force over an area of 0.00064516 square meters. This unit is commonly used in the United States for engineering and mechanical applications, particularly in contexts involving heavy machinery and structural engineering, where high pressures are prevalent.
Current Use
Currently, the ton force per square inch is primarily used in the United States in various engineering applications, particularly in mechanical and civil engineering contexts. It provides a convenient way to express high pressures when dealing with large machinery, hydraulic systems, and structural loads.
Fun Fact
The ton force per square inch is not widely used outside the United States, where the metric system is preferred.

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'.

Ton Force per Square Inch
pressure • Non-SI
Definition
The ton force per square inch (tf/in²) is a non-standard unit of pressure that denotes the pressure exerted by a force of one short ton (2,000 pounds) distributed evenly over an area of one square inch. In SI terms, this value is equivalent to 2,000 pounds-force over an area of 0.00064516 square meters. This unit is commonly used in the United States for engineering and mechanical applications, particularly in contexts involving heavy machinery and structural engineering, where high pressures are prevalent.
History & Origin
The concept of measuring pressure dates back to the early studies of fluid mechanics, with notable advancements in the 17th century. The ton force, as a unit of weight, was established in the United States in the 19th century, leading to the derivation of ton force per square inch as a pressure unit.
Etymology: The term 'ton' is derived from the Old English 'tun,' referring to a large cask or barrel, while 'force' indicates the influence that produces or alters motion. The term 'inch' comes from the Latin 'uncia,' meaning one-twelfth of a foot.
Current Use
Currently, the ton force per square inch is primarily used in the United States in various engineering applications, particularly in mechanical and civil engineering contexts. It provides a convenient way to express high pressures when dealing with large machinery, hydraulic systems, and structural loads.
💡 Fun Facts
- •The ton force per square inch is not widely used outside the United States, where the metric system is preferred.
- •One ton force per square inch is equivalent to approximately 138,000 pascals.
- •The term 'ton' can refer to either a short ton (2,000 pounds) or a long ton (2,240 pounds), so context matters.
