There are 760 torr in 1 atmospheres. Exactly 1 atm is equal to 760 Torr.
The conversion formula is: Torr = Torr = atm × 760. Applying this to 1 atm gives: 1 × 760 = 760 Torr.
To convert in reverse from torr to atmospheres, multiply by the inverse factor: 1 Torr = 0.001316 atm. Alternatively, divide your Torr amount by 760.
To calculate in your head, round the conversion multiplier (760) to the nearest easy whole or decimal number.
