Torr to atm Converter - Torr to Standard Atmosphere

Torr (Torr) to Standard Atmosphere (atm)

Direct answer

1 Torr = 0.001315785838 atm

atm = Torr × 0.001315785838

Converter

Input

Torr

Result

0.001315785838atm

atm = Torr × 0.001315785838

Torr = atm × 760.002100179

Example: 10 Torr = 10 × 0.001315785838 = 0.013157858377 atm.

Express both Torr and atm in the same base unit Pa (pascal), then cancel the shared base unit.

1
Rewrite Torr in the base unit
$1 Torr = 133.322 Pa$
2
Rewrite atm in the base unit
$1 atm = 101, 325 Pa$
3
Forward conversion
$1 Torr = \frac{133.322 Pa}{101 , 325 Pa} \times 1 atm = \frac{133.322}{101 , 325} atm = 0.001315785838 atm$
4
Reverse conversion
$1 atm = \frac{101 , 325 Pa}{133.322 Pa} \times 1 Torr = \frac{101 , 325}{133.322} Torr = 760.002100179 Torr$
