How many torr are in one atmosphere?
One standard atmosphere is exactly 760 torr.
Detailed answer
By definition, 1 torr = 1/760 of a standard atmosphere, so 1 atm = 760 torr. In pascal, 760 × (101325/760) = 101,325 Pa.
Relationship context
Torr remains standard in vacuum science; atm links to historical chemistry and STP discussions.
