Kilopound per Square Inch
Definition and History
The kilopound per square inch (KSI) is a unit of pressure equal to one thousand pounds of force applied to one square inch of area. It is a specialized unit commonly used in high-pressure engineering applications, particularly in aerospace, structural engineering, and materials science, providing a practical unit for measuring very high pressures in various industrial and scientific applications.
KSI was developed as part of the imperial system of units for measuring extremely high pressures that would be impractical to express in PSI. This unit offers a practical scale for high-pressure measurements, making it easier to understand and communicate pressure values in aerospace, structural engineering, and materials science contexts where very high pressures are common.
KSI is equivalent to 6,894,760 pascals or 6.89 megapascals, making it a specialized unit for measuring very high pressures in aerospace engineering, structural analysis, materials testing, and other applications where the imperial system is used and extremely high pressures are encountered.
