Meaning and Definition
Abbreviation for 'Standard Temperature and Pressure', a standard reference set of conditions used in scientific measurements, especially in chemistry and physics.
A standardized set of reference conditions (typically 0°C and 1 atm pressure) used to compare measurements of gas properties. It provides a consistent baseline for experiments and calculations.
Dialectal Variation
British vs American Usage
Differences
None; the abbreviation and its referent are identical in scientific communities. British English sometimes uses 'SATP' (Standard Ambient Temperature and Pressure) for a different modern standard.
Connotations
Purely technical, academic, or scientific.
Frequency
