SponsoredThis converter turns ksi into megapascals (ksi to MPa). Enter a value and the result updates as you type. 1 ksi is about 6.894757 megapascals.
KSI and megapascals are both used for material strength and stress: ksi in the US, MPa in metric countries. 1 ksi is exactly 1,000 psi, since a kip is 1,000 pounds of force. In metric units that is about 6.894757 MPa, so a strength written in MPa is roughly seven times the same strength in ksi.
The result shows 0 for a negative entry. A compressive stress is sometimes written as negative; convert its size here and keep the sign yourself. The result is rounded to 4 decimal places.
How to Convert KSI to Megapascals
To convert ksi to megapascals, multiply by about 6.894757. For example, 36 ksi is about 248.2113 MPa.
To go from megapascals back to ksi, divide megapascals by about 6.894757, or multiply by about 0.1450377.
KSI to Megapascals Conversion Table
Common ksi values converted to megapascals, rounded to 4 decimal places.
| KSI | Megapascals |
|---|---|
| 1 ksi | 6.8948 MPa |
| 5 ksi | 34.4738 MPa |
| 10 ksi | 68.9476 MPa |
| 20 ksi | 137.8951 MPa |
| 30 ksi | 206.8427 MPa |
| 36 ksi | 248.2113 MPa |
| 50 ksi | 344.7379 MPa |
| 60 ksi | 413.6854 MPa |
| 80 ksi | 551.5806 MPa |
| 100 ksi | 689.4757 MPa |
| 120 ksi | 827.3709 MPa |
| 150 ksi | 1,034.2136 MPa |
KSI and MPa for Material Strength
Material strengths appear in ksi in US units and in MPa, or N/mm², which is the same number as MPa, in metric units. A quick estimate is to multiply ksi by 7, but that overstates the result by about 1.5%, so use the full factor for anything written down.
Bending stress in a beam is one of these quantities, and the Bending Stress Calculator returns it in psi; divide by 1,000 for ksi. Concrete strength is also specified in MPa or psi, while the Concrete Cylinder Calculator works out the concrete volume for a round column.
Frequently Asked Questions
What is 150 ksi in MPa?
150 ksi is about 1,034.21 MPa.
What is 36 ksi in MPa?
36 ksi is about 248.21 MPa.
How do I convert MPa to ksi?
Divide MPa by about 6.894757, or multiply by about 0.1450377. For example, 250 MPa is about 36.26 ksi.
Is the KSI to Megapascals factor exact?
The factor is fixed by definitions, so it never changes, but it has no finite decimal form. 1 ksi is about 6.894757 megapascals. The calculator uses the full value and rounds only the result it shows.
What happens if I enter a negative value?
It shows 0. To convert a compressive stress written with a minus sign, enter the size without the sign and add the sign back to the result.
