The Core (2003)

Factual error: In a few shots through the movie the gauges or screens displaying information, they use "PPI" for pounds per sq. inch instead of PSI. PPI is wrong it's always PSI. The first time you see it is in the scene when they just launch the ship right before they pierce the crust with Braz and Serge for sure.

Suggested correction: They are measuring pounds per linear inch which is PPI.

Pounds per Linear Inch is PLI, not PPI.

Pressure is defined as force over area. Any force (i.e, pounds) over any area (length × width, i.e. inches squared or meters squared or...squared) as defined in 1961 if not earlier.
