What is a poundal per square foot?

It is a pressure unit defined as one poundal of force uniformly applied over one square foot, used mainly in the FPS system.

Why convert poundal/square foot to ksi?

Converting to ksi allows pressure values from legacy FPS data to be used in modern engineering stress calculations common in materials and structural engineering.

No, ksi is a non-SI unit commonly employed in engineering to express stress, equal to 1,000 pounds-force per square inch.
