Pounds per Square Inchpsi
Source UnitPsi or 'pounds per square inch' is a unit used to measure pressure. It defines the pressure resulting from a force of one pound-force applied to an area of one square inch. As a non-SI unit, it is commonly used in the United States and other countries still employing the Imperial system. Psi is vital in various engineering and mechanical applications, providing a practical measure for pressure in car tires, hydraulic systems, and more. It offers a direct relationship to other pressure units through conversion factors.
Current Use
Today, psi is extensively used in various fields, particularly in the United States. It is prevalent in automotive applications, where it measures tire pressure, ensuring safety and performance. Additionally, psi is crucial in aerospace, measuring cabin pressure and hydraulic systems. In industrial settings, it is used for pressure gauges, compressors, and pneumatic tools. Despite the global trend towards SI units, psi's practical relevance maintains its usage in specific regions and industries.
Fun Fact
Psi is still a preferred unit in U.S. automotive manuals.
Kips per Square Inchksi
Target UnitThe kilopound per square inch (ksi) is a unit of pressure defined as a force of 1,000 pounds applied uniformly over an area of one square inch. It is commonly used in engineering, particularly in the fields of materials science and structural engineering, to express the strength of materials and the stress they can withstand before failure. The ksi is part of the imperial system of units, where pressure is often evaluated in pounds per square inch (psi), making the conversion straightforward as 1 ksi equals 1,000 psi.
Current Use
Currently, ksi is widely used in the fields of structural and mechanical engineering, where it is essential for specifying material strengths and loads in design calculations. It is particularly prevalent in the United States, where imperial units are standard. The ksi is utilized in various industries, including construction, aerospace, and automotive engineering, to evaluate and communicate the mechanical properties of materials and their performance under stress.
Fun Fact
The kip is a commonly used unit in American engineering, but it is rarely found in everyday conversation.

Kips per Square Inch
pressure • Non-SI
Definition
The kilopound per square inch (ksi) is a unit of pressure defined as a force of 1,000 pounds applied uniformly over an area of one square inch. It is commonly used in engineering, particularly in the fields of materials science and structural engineering, to express the strength of materials and the stress they can withstand before failure. The ksi is part of the imperial system of units, where pressure is often evaluated in pounds per square inch (psi), making the conversion straightforward as 1 ksi equals 1,000 psi.
History & Origin
The use of the ksi as a unit of pressure emerged in the 20th century, particularly gaining traction in the fields of civil and mechanical engineering. It was adopted as a convenient measure to express the high strength of materials such as steel and concrete, which often operate under significant loads. The transition from psi to ksi allowed engineers to simplify their calculations and present results in a more manageable numerical format, especially when dealing with large numbers.
Etymology: The term 'kip' is derived from 'kilopound,' which denotes a weight of 1,000 pounds. This term was coined to provide a more concise terminology for expressing large forces in engineering contexts.
