What does 1 Torr represent in standard atmosphere units?

1 Torr is equal to approximately 0.0013157895 standard atmospheres, representing a fraction of atmospheric pressure.

When should I use Torr instead of atm?

Torr is typically used for measuring low pressures and vacuum levels, while atm is suited for representing average atmospheric conditions.

Can local atmospheric pressure variations affect my conversion?

Yes, the conversion assumes exact unit definitions and does not consider local atmospheric changes, which may influence actual pressure readings.
