GSC is a unit of measure describing pressure in grams per square centimeter.
Comparative measurements of pressure
Klingon Template:ShipClass being crushed by external pressure exceeding 15,000 GSC.
- Apollo's hand was capable of creating over 1,000 GSC of external pressure on the hull of the USS Enterprise. Above 1,000 GSC, and the systems aboard a Template:ShipClass start to become critical. (TOS: "Who Mourns for Adonais?")
- A Klingon Template:ShipClass warship is capable of withstanding atmospheric pressure of 15,000 GSC, or that found in a Class 9 gas giant approximately 2 kilometers in its atmosphere. That pressure is also well within the tolerance of a 22nd century Earth Starfleet shuttlepod. (ENT: "Sleeping Dogs")
- Template:ShipClass starship are capable of withstanding a hull pressure exceeding 9,000,000 GSC. (DS9: "Starship Down")
