What are the standard conditions for gas measurements? - Quora

Well for starters, one standard set of conditions: Standard Temperature and Pressure (STP) is 0C and 1 atm.

STP vs Standard State Conditions

STP describes Standard Conditions. STP is often used for measuring gas density and volume using the Ideal Gas Law . Here, 1 mole of ideal gas occupies 22.4 L. Note: An older definition used atmospheres for pressure, while modern calculations are for pascals.
