🏗️ ksi → MPa Converter
Translate structural stress values from imperial to metric units.
Engineers and material scientists use this conversion to compare U.S. structural ratings with SI design standards.
30 ksi equals
206.842719 MPa
Gigapascals: 0.206843 GPa
psi: 30,000
How to Use This Calculator
Enter ksi
Provide the stress or pressure value in kips per square inch.
Review MPa
The converter multiplies by 6.89476 to output MPa.
Use additional units
Gigapascals and psi help compare across multiple specifications.
Formula
MPa = ksi × 6.89476
GPa = MPa ÷ 1,000
psi = ksi × 1,000
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Structural steel, concrete, and fastener ratings in the U.S. often use ksi. Metric codes rely on megapascals. This converter removes the friction when comparing or converting designs between standards.
Including gigapascals offers a quick check for very high-strength materials, while psi keeps a link to the original imperial units.
Frequently Asked Questions
What is a kip?
A kip equals 1,000 pounds-force. KSI measures thousands of psi.
Can I convert MPa back to ksi?
Divide MPa by 6.89476, or use this page by entering the MPa value after rearranging the formula.
Does it support decimals?
Yes. Decimal ksi values convert accurately into MPa and GPa.
Are results rounded?
Outputs use standard engineering precision. Adjust formatting if needed.
