ksi = psi ÷ 1,000 (1 ksi = 1,000 psi).
| psi | ksi |
|---|---|
| 100 | 0.1 |
| 500 | 0.5 |
| 1,000 | 1 |
| 4,000 | 4 |
| 36,000 | 36 |
| 50,000 | 50 |
Divide psi by 1,000. Example: 4,000 psi concrete = 4 ksi.
Kips per square inch. 1 kip = 1,000 lbf, so 1 ksi = 1,000 psi.
Divide psi by 145.04. Example: 36,000 psi = 248.2 MPa.
