Standard Atmosphere (atm)
The standard atmosphere (atm) is defined as exactly 101,325 pascals — average sea-level atmospheric pressure.
Atmospheres compare scuba tank fills, describe laboratory reference pressure, and normalize gas volumes.

About these units
Short background on the units used in this conversion.
Torr
The torr is a pressure unit equal to 1/760 of a standard atmosphere, matching 1 mmHg at 0°C within rounding.
Torr measures vacuum levels in chemistry, semiconductor fabrication, and high-vacuum physics experiments.
