what is ksi unit

Ksi is a unit of pressure measurement that stands for kilopounds force per square inch. It is derived from the psi pressure unit by multiplying it by 1,000, and the full name is kilopounds force per square inch. Ksi is an Imperial unit of measurement and is not widely used for gas pressures. It is mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa = 0.145 ksi.
