How to Convert Ksi to Mpa

By Lisa Porter

Ksi is a unit of measurement referring to pressure, specifically the kilopound-force per square inch exerted on an object. This unit is often used in materials science and engineering to measure stress. One ksi equals 1000 psi, or pound-force per square inch. The MPa, or megapascal, is another unit of measurement for pressure. You can convert a ksi value to an MPa value with a calculator and simple multiplication or division or you can use a free online unit conversion calculator.
