Formula
ksi = MPa × 0.1450377
Multiply any value in megapascals by 0.1450377 to obtain the value in kilopounds-force per square inch.
Worked example
Convert 100 MPa to ksi.
- 01Start with 100 MPa.
- 02Multiply by the conversion factor: 100 × 0.1450377 = 14.5038 ksi.
Result100 MPa = 14.5038 ksi

FAQ
What is the conversion factor from MPa to ksi?
1 MPa equals 0.1450377 ksi. To convert, multiply the value in megapascals by 0.1450377.
How do I convert 1 MPa to ksi?
1 MPa = 0.145038 ksi. For any value, multiply by 0.1450377.
How do I convert ksi back to MPa?
Divide by the same factor — or equivalently, multiply by 6.894757. So 1 ksi = 6.89476 MPa.
When would I need to convert megapascal to kilopound-force per square inch?
Pressure conversions between MPa and ksi are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
