Gigapascals to Kilopounds per square inch converter

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

1 GPa ≈ 145.03773773 ksi
1 ksi ≈ 0.00689475729317 GPa

Formula: ksi ≈ GPa × 145.03773773
GPa ≈ ksi × 0.00689475729317

Definitions: 1 GPa = 1000000000 Pa; 1 ksi = 1000 psi

The gigapascal (GPa) is one billion pascals. It is used for very high stresses and for stiffness (Young's modulus), where steel is about 200 GPa, and for pressures deep inside the Earth.

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.
