Factor1 kPa = 0.0001450377 ksi

Converter

kPa

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

Result
14.5038ksi

Rendered to 6 significant figures.

Formula

Formula
ksi = kPa × 0.0001450377

Multiply any value in kilopascals (stress) by 0.0001450377 to obtain the value in kilopounds-force per square inch (stress).

Worked example

Convert 100000 kPa to ksi.

  1. 01Start with 100000 kPa.
  2. 02Multiply by the conversion factor: 100000 × 0.0001450377 = 14.5038 ksi.
Result100000 kPa = 14.5038 ksi

FAQ

What is the conversion factor from kPa to ksi?
1 kPa equals 0.0001450377 ksi. To convert, multiply the value in kilopascals (stress) by 0.0001450377.
How do I convert 1 kPa to ksi?
1 kPa = 0.000145038 ksi. For any value, multiply by 0.0001450377.
How do I convert ksi back to kPa?
Divide by the same factor — or equivalently, multiply by 6894.757. So 1 ksi = 6894.76 kPa.
When would I need to convert kilopascal (stress) to kilopound-force per square inch (stress)?
Stress conversions between kPa and ksi 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).
