What is a picopascal (pPa)?

A picopascal is an SI-derived unit representing pressure equal to 10⁻¹² pascals, used for measuring extremely small force per unit area.

Where is ton-force (long)/square foot pressure used?

It is used in older imperial engineering contexts such as foundation bearing pressure, shipbuilding load capacity, and heavy industry specifications.

Why are converted values from pPa to ton-force (long)/square foot so small?

Because picopascal measures very low pressures, conversions result in tiny fractional values due to scale differences between the units.
