Basis
Saturated liquid at 60°F per GPA/NFPA 58. Strongly temperature-dependent — the industry corrects deliveries to 60°F for exactly this reason. Liquid weight excludes the container — add tare weight for transport math. Matching tank charts: 55 gal tank · 275 gal tank · 330 gal tank · 500 gal tank · 1000 gal tank.
