Megapascals to Kips per square inch
1 megapascal = 0.14504 kips per square inch · 1 ksi = 6.8948 MPa
1 megapascal = 0.14504 kips per square inch
How it’s calculated
ksi = MPa × 0.1450377377
- Multiply the value in megapascals by 0.1450377377.
- To go back, divide by 0.1450377377 (or multiply by 6.894757293).
- 1 MPa = 0.1450377377 ksi · 1 ksi = 6.894757293 MPa

Find the conversion factor
By definition 1 MPa = 1000000 Pa and 1 ksi = 6894757.29316836 Pa, so 1 ksi = 6.89475729316836 MPa. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units); NIST SP 811 / Handbook 44.
Multiply by the factor written as a fraction
Put MPa in the denominator so it cancels, leaving ksi.
