Explanation
torr and atmospheres are units of pressure. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 torr = 0.0013157895 atmospheres, and 1 atmospheres = 760 torr. Because one atmospheres represents a larger amount than one torr, the numeric value gets smaller in this direction.
How to convert torr to atmospheres
- Enter the value in torr (Torr).
- Multiply it by 0.0013157895.
- The result is the equivalent value in atmospheres (atm).
- Round the result if needed.
Worked example
