ksi (kilopound per square inch) is a common stress / pressure unit in structural and mechanical engineering, especially in the United States. MPa (megapascal) is widely used in SI-based design codes. The conversion is based on the relationship between pound-force, inch, and pascal.
1 ksi = 6.894757 MPa (approximately)
pressure (MPa) = pressure (ksi) × 6.894757
For the reverse conversion:
1 MPa ≈ 0.145038 ksi
pressure (ksi) = pressure (MPa) ÷ 6.894757
Here are a few practical examples based on typical material strengths and structural loads:
MPa = 36 ksi × 6.894757 ≈ 248.21 MPa
So 36 ksi ≈ 248.2 MPa.
MPa = 50 ksi × 6.894757 ≈ 344.74 MPa
So 50 ksi ≈ 344.7 MPa.
ksi = 250 MPa ÷ 6.894757 ≈ 36.26 ksi
So 250 MPa ≈ 36.3 ksi.
This table lists common ksi values and their approximate equivalents in MPa, using 1 ksi = 6.894757 MPa. Rounded to two decimal places for quick reference.
| Stress (ksi) | Stress (MPa) |
|---|---|
| 10 ksi | 68.95 MPa |
| 20 ksi | 137.90 MPa |
| 30 ksi | 206.84 MPa |
| 36 ksi | 248.21 MPa |
| 50 ksi | 344.74 MPa |
| 60 ksi | 413.69 MPa |
| 70 ksi | 482.63 MPa |
| 100 ksi | 689.48 MPa |
ksi and MPa appear in many engineering contexts where material strength, stress, and allowable loads are specified:
Many steel grades in US design practice are specified in ksi (e.g. 36 ksi, 50 ksi). International standards often use MPa (e.g. 250 MPa, 345 MPa). Converting between ksi and MPa is essential for comparing specifications.
Load combinations, allowable stresses, and design resistance may be provided in different units across codes, software, and manufacturer datasheets. A fast ksi–MPa converter reduces the risk of unit errors.
FEA software often works in SI units (MPa), while test reports or legacy data may be in ksi. Converting your material properties and results correctly ensures consistent inputs and interpretation.
Engineering students frequently need to convert between ksi and MPa in homework, lab reports, and exam preparation. Step-by-step solutions help verify understanding, not just the final number.
Multiply the ksi value by 6.894757: MPa = ksi × 6.894757.
Divide the MPa value by 6.894757: ksi = MPa ÷ 6.894757.
ksi is part of the imperial unit system and is traditional in North American structural and mechanical design. MPa is the SI-based unit commonly used in international standards and metric countries.
The converter uses a standard factor 1 ksi = 6.894757 MPa, which is accurate for most engineering purposes. For safety-critical design, always follow the rounding rules and safety factors required by your design code or company standards.
