A 10 L ideal-gas volume already at 0 °C and 1013.25 hPa remains 10 L under this conventional STP definition.

V_STP = V × (273.15/T) × (P/760); n = PV/(62.36T), with V in L, P in Torr and T in K.

Enter these known values and leave the other values blank.

This tool defines conventional STP as 273.15 K and 760 Torr (one standard atmosphere). Other standards use 100 kPa; confirm the convention for your work.
Pressure is absolute, temperature is absolute internally and volume must be positive. Use gauge-pressure measurements only after converting to absolute pressure.
The gas is ideal, dry and conserved between states. Real gases and wet-gas measurements require additional corrections.
The captured gas constant is rounded to 62.36 L·Torr/(mol·K). The hidden n1 and moles values represent the same gas amount; no uncertainty is propagated.

Zero degrees Celsius and one standard atmosphere, represented as 760 Torr.

No. Subtract the appropriate water-vapor partial pressure before entering dry-gas pressure.

Declare the physical or stated approximation domain; captured arithmetic is unchanged.
