Torr to ATM Converter
Convert pressure measurements between torr and atmospheres
Pressure Conversion Formulas
1 Atmosphere (atm) = 760 Torr
This exact relationship is fundamental for pressure conversions in chemistry and physics.
Torr to Atmospheres
atm = torr ÷ 760
Atmospheres to Torr
torr = atm × 760
Torr to mmHg
1 torr = 1 mmHg (by definition)
mmHg to Atmospheres
atm = mmHg ÷ 760
Understanding Pressure Conversions: Torr to ATM
When working with pressure measurements in scientific and engineering applications, you'll often need to convert torr to atm or vice versa. Our converter makes these calculations simple and precise.
Common Conversion Scenarios:
- 760 torr to atm equals exactly 1 atm (760 ÷ 760 = 1)
- 1 atm to torr equals exactly 760 torr (1 × 760)
- 380 torr to atm equals 0.5 atm (380 ÷ 760)
- 2 atm to torr equals 1520 torr (2 × 760)
When to Use Each Unit:
Torr
Commonly used in vacuum measurements, barometry, and blood pressure (though mmHg is technically used for blood pressure). Named after Evangelista Torricelli, inventor of the barometer.
Atmospheres (atm)
Standard reference pressure equal to average atmospheric pressure at sea level. Used in chemistry, physics, and engineering as a reference pressure.
