About Converting Megapascals to KSI
Megapascal and KSI both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Megapascal is 1000000 pascal units, and kips per square inch.
Formula
ksi = megapascals × 0.14503773773
This factor comes from each unit's defined relationship to the category's base unit: 1 megapascal equals 1000000 base units, and 1 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct megapascal-to-ksi factor of 0.14503773773.
Simple example
1 MPa × 0.1450377377 = 0.1450377377 ksi
1 megapascal = 0.1450377377 ksi.
Real-world example
35 MPa × 0.1450377377 = 5.076320821 ksi
35 megapascals = 5.076320821 ksi.
