Kilopounds per square inch to Megapascals converter

To convert kilopounds per square inch to megapascals, enter the value in the first field. The result in megapascals is calculated automatically using the exact conversion factor.

1 ksi ≈ 6.89475729317 MPa
1 MPa ≈ 0.14503773773 ksi

Formula: MPa ≈ ksi × 6.89475729317
ksi ≈ MPa × 0.14503773773

Definitions: 1 ksi = 1000 psi; 1 MPa = 1000000 Pa

The kilopound per square inch (ksi) is 1,000 psi. It is used in United States structural and materials engineering for the strength of steel and concrete, for example steel with a yield strength of 36 or 50 ksi.

The megapascal (MPa) is one million pascals, or one newton per square millimeter. It is the standard unit for material strength, hydraulic pressure and high-pressure equipment, and for stress in steel and concrete.
