What is a poundal per square foot?

It is a pressure unit in the FPS system, representing one poundal of force applied uniformly over one square foot of area.

What does a gigapascal measure?

A gigapascal measures pressure or mechanical stress equal to 10^9 pascals, often used for very high pressures in engineering and materials science.

Why convert poundal/square foot to gigapascal?

To translate legacy, low-magnitude FPS pressures into modern SI units for high-precision engineering and scientific analysis.
