How to convert Torr to Atmosphere
Multiply the torr value by 0.00131579: 1 Torr = 0.00131579 atm. Going the other way, 1 atm = 760.002 Torr, so divide by 0.00131579 or use the Atmosphere to Torr converter.
About these units
Torr (Torr)
A torr is 1/760 of a standard atmosphere, about 133.3 pascals, and is nearly identical to a millimeter of mercury. It is common in vacuum work.
Atmosphere (atm)
A standard atmosphere is defined as exactly 101,325 pascals, roughly the average air pressure at sea level. It is about 14.7 psi or 1.013 bar.
