What does psi/1000 feet represent?

Psi/1000 feet is a measure of pressure gradient that shows how pressure changes in pounds-force per square inch for every 1,000 feet of depth, used to infer fluid density in drilling contexts.

Why convert psi/1000 feet to pound per cubic inch?

Converting to pound per cubic inch provides a density unit compatible with mass per volume measurements in imperial units, important for engineering and material calculations.

Can this conversion measure static fluid density?

No, psi/1000 feet relates to pressure gradients rather than direct measurement of static fluid density.
