A standard atmosphere is a pressure unit defined as exactly 101,325 pascals.
The atmosphere unit became useful as a reference for average sea-level air pressure in science and education.
atm is used in chemistry, gas laws, diving references, laboratory work, classroom problems, and pressure comparisons.
A torr is a pressure unit defined as 1/760 of a standard atmosphere.
Torr is named after Evangelista Torricelli and remains associated with mercury-column and vacuum pressure measurement.
Torr is used in vacuum systems, laboratories, physics, chemistry, pressure gauges, and low-pressure process documentation.
Mathematically, torr (Torr) = standard atmosphere (atm) converted with the formula below.
1 atm = 760 Torr
1 Torr = 0.001316 atm
Formula: value × 760
Example: 15 atm = 11,400 Torr
Precision note: Use exactly 760 Torr per atm. Preserve decimals when converting fractional atmosphere values.
1 atm = 760 Torr
1 Torr = 0.001316 atm
