STP

Chemistry's reference state

STP is an abbreviation with several meanings depending on context.

In chemistry and physics, it stands for standard temperature and pressure—the reference conditions (typically 0°C and 1 atmosphere) used to compare gas measurements.

In automotive contexts, STP is a brand of motor oil additives and fuel treatments.

STP is also slang for a powerful hallucinogenic drug (2,5-dimethoxy-4-methylamphetamine), named after the motor oil additive to suggest its potency.
