Stress

ksitoMpsi

Convert kilopounds-force per square inch (stress) (ksi) to megapounds-force per square inch (stress) (Mpsi).

Factor1 ksi = 0.001 Mpsi

Converter

ksi

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1Mpsi

Rendered to 6 significant figures.

Formula

Formula
Mpsi = ksi × 0.001

Multiply any value in kilopounds-force per square inch (stress) by 0.001 to obtain the value in megapounds-force per square inch (stress).

Worked example

Convert 1000 ksi to Mpsi.

  1. 01Start with 1000 ksi.
  2. 02Multiply by the conversion factor: 1000 × 0.001 = 1 Mpsi.
Result1000 ksi = 1 Mpsi

FAQ

What is the conversion factor from ksi to Mpsi?
1 ksi equals 0.001 Mpsi. To convert, multiply the value in kilopounds-force per square inch (stress) by 0.001.
How do I convert 1 ksi to Mpsi?
1 ksi = 0.001 Mpsi. For any value, multiply by 0.001.
How do I convert Mpsi back to ksi?
Divide by the same factor — or equivalently, multiply by 1000. So 1 Mpsi = 1000 ksi.
When would I need to convert kilopound-force per square inch (stress) to megapound-force per square inch (stress)?
Stress conversions between ksi and Mpsi are routine in mechanics-of-materials work: yield, ultimate and allowable-stress specification, Young's-modulus tables and structural-design code calculations. MPa and N/mm² dominate ISO and European datasheets, psi and ksi dominate US structural codes, and kgf/cm² and kgf/mm² appear in legacy JIS and heavy-engineering documentation. Stress is the same physical dimension as pressure but a different engineering quantity — this category is mechanics-of-materials, not process pressure.
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).
