Atmospheres to Torr converter

To convert atmospheres to torr, enter the value in the first field. The result in torr is calculated automatically using the exact conversion factor.

1 atm = 760 Torr
1 Torr ≈ 0.00131578947368 atm

Formula: Torr = atm × 760
atm ≈ Torr × 0.00131578947368

Definitions: 1 atm = 101325 Pa; 1 Torr = 20265/152 Pa

The standard atmosphere (atm) is exactly 101,325 pascals, the average air pressure at sea level. It is a reference pressure in chemistry and physics and is used to express high pressures as multiples of atmospheric pressure.

The torr is 1/760 of a standard atmosphere, very close to the pressure of one millimeter of mercury. It is used in vacuum technology and physics, where pressures below atmospheric are given in torr or millitorr.
